No, you have to purchase SMA sockets with wires to put onto the back of the unit (so that you can screw in some antennae), and then solder each of the antenna wires to each pair of solder pads. DO NOT connect them together. Basically, you need to make new connectors for them.

Similar to what was done in this thread: https://xdaforums.com/android-auto/...-development/mtcd-add-2-wifi-antenna-t3648605

Stock, my unit didn't even have an antenna connected to one of the sets of solder points, and the other antenna was a crappy piece of wire.

Yes. That is where the PX5 CPU is. How do I know? Because that is the daughter-board that PX3->PX5 upgrades replace. I wouldn't worry about the other ICs. It's primarily the CPU that needs extra cooling. I decided to use a passive heatsink only for now because these IC's are relatively low wattage (in general). That said, the little RF shield/Heat shield is too tiny to dissipate heat so, a larger surface is needed. How large? I'm using an old Pentium 2 or 3 heatsink that looks like this: http://www.techzonics.com/pentium-ii-cpu-aa.jpg. I'm guessing that will dissipate enough heat passively. Putting in a small fan, although a good idea for cooling, is probably not so good for EMI.

I'll do some thermal testing/logs later to see how my temperatures are.
[MTCD Android Head Units General] While2>1Confused:
I thought that would be mental! Photo just looked like they where!

I'll head off to eBay to buy an extra sma socket, male<>female extension cables and a pair of antennas (I have ine WiFi small socket in the back already)

Many thanks indeed :)

Ok so I have a hot audio/dasaita headunit, and I want to be able to add my sim card to it. I have project Fi as my carrier and the data sim they have uses T-Mobile towers. The problem I am having is that I can't find a USB Sim card adapter that will work with both the headunit and my sim card. I have one that kind of works. It will sometimes connect and give me signal but it can only connect with a built-in wifi emitter it has. I want one that will connect over USB and register on the headunit. Anyone know of any adapter that would work?
[MTCD Android Head Units General] typos1:
Cusptech is the company.

Your problem was you only had 1 antenna - the chip is dual wifi/BT and only having one antenna means only one thing can work at the same time. All antennas are "pieces of wire" so the problem was not the quality of wire, it was the that it only had one wire, if you added a piece of wire exactly the same as the other to the other pads it would have also solved the problem. Of course the length of wire would improve the signal too.

You urgently need to secure the heatsink with screws using the holes provided, if it comes loose it could short circuit lots of things and destroy your unit, it is not a good idea for anyone to put a heatsink anywhere in their unit without securing it with screws - we re talking devices mounted in cars and trucks that could easily end up shaking a heatsink stuck in with superglue loose - superglue is a brittle adhesive.

Do you have an sd card or usb stick with an update on in your unit ?

Hello,

I have the following problem. I want to connect the steering wheel buttons (resistance controlled) to my Xtrons TB706PL head unit. The problem is, that also the horn is connected over the same wires as the steering wheel buttons, so I can’t cut them off the other Controllers of the Car. If I connect now the steering wheel buttons to the Key1 and GND cable the horn goes off permanently (due to voltage between Key1 and GND). Is there any other opportunity to connect the buttons, for example via CAN?
[MTCD Android Head Units General] typos1:
You dont ahve an Xtrons unit - Xtrons are sellers only - they stick their badges on units they buy from manufactures, to see what unit you have go to settings/about device,. the letters after "MTCD" will tell you what unit you have.

If your car has resistive SWC then you cannot use CAN Bus, what car do you have ? I would search forums about that car for how to wire up SWC on aftermarket head units - these Android ones are the same as any other in that respect.
[MTCD Android Head Units General] jukimukikuki:
Hi, sorry, I have a GS Unit, forgotten to write that ;)

I have a Saab 9-5, the resistance measurement cables are coming from the Steering wheel to the central controller of the car. There I have connected the Radio, but because of the voltage it’s generating to measure the resistance the controller of the Car thinks the Horn is pressed.

The original radio of the Car got the steering wheel button information’s over CAN. The central controller is interpreting the resistance measurement and sends a message on the CAN which button is pressed.
[MTCD Android Head Units General] ikerg:
My mazda CX 5 has resistive swc wires...and they work if directly wired to headunit (as I had before having cx5 specific unit) and if plugged to can bus .

When I had a universal mtcd unit i tried to plug them directly or through the rp4-mz11 can-bus box and the unit detected different signals...(any resistance conversion from.the old can-bus to adapt to standard swc resistive signals)

[MTCD Android Head Units General] typos1:
Ok, if the car originally got its SWC info from CAN, then trying to use the resistive inputs wont work, did you get a CAN Bus decoder with the unit ? If not you will have to buy a SWC adapter, I have read that these units use the Pioneer SWC protocol, although I have not heard this confirmed.

---------- Post added at 12:05 PM ---------- Previous post was at 12:03 PM ----------

Yes, my car also is CAN Bus but has resistive SWC, but I think in [MENTION=4305332]jukimukikuki[/MENTION]'s case he should connect SWC the same way as the factory do.

There are no "Witson" units, Witson are a seller, they buy from manufacturers and sell them on, to find out what unit you have go to settings/about device, the letters after "MTCD" will tell you what unit you have.

When you know this you can then work out what MCU you can use.

Each manufacturer establish their own updates for mcu....and they don't provide any changelog....so you have to discover by yourself what news are included...normally they include support for new can-bus boxes (new headunit model) and slight new improvements (like HA when introduced the sleep delay option)

Problems with my GPS

Hello guys , i got this Android GPS : http://www.ebay.fr/itm/Autoradio-GPS-android-6-1-Android-CITROEN-C4-et-DS4/322588577611?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

I think it’s an witson B5626 .

My car is a Citroen C4 II from 2011 and I have connect the canbus 2008 that is come in the box of the GPS .

I got problems using the steering wheels remote and with the A/C informations displayed on the the screen !

For the remote :

-the next and previous are reverse and I need to press the scroll wheel before the gps detect actions , when I scroll the wheel to the down it give me the next track and when I scroll to top it give the previous , with my original GPS it was top = next and down = previous ) .

- Nothing appears in the remote manager .

For the A/C informations :

-	My A/C on the dashboard said for example 14°C but the screen display said it’s 16°C , the degrees are always increment by 2 points what is wrong ?

Here is a video that show you the 2 last problems :

https://www.youtube.com/watch?v=ye2hQSCw794

How can i fix that ? By updates ?

Here is pictures about my systems information :

Best regards , Astobelix .

[MTCD Android Head Units General] typos1:
NO ! I have said already WITSON ARE A SELLER ONLY - MX is the name of the manufacturer, Witson sell units from lots of different manufacturers, Witson DOES NOT = MX.

You can say "If it aint broken.. Dont fix it", buit this is NOT how things work with computers, it is best practise to update to new versions when they are available and only go back to the old version if there is a problem.

No, Witson are a seller, to find out what unit you have go to settings/about device, the letters after "MTCD" will tell you what unit you have.

Why is it that people DO NOT read before they post ?

If you want to spend hour figuring it out maybe, I explained the solution in my previous post, but I would search the Saab forums about how to sort it out - these units behave exactly the same as any other car stereo when it comes to interfacing with the SWC, so the solution will be the same.

T-Mobile ZTE hotspots (Z915/Z917) will work with a Google Fi SIM out of the box, and I think can be configured to disable wifi, and just work as a USB modem. I don't know if they work with the Dasaita head unit directly though. I don't have any USB ports passed through with my Dasaita install to test, unfortunately.

Any reason you don't want to use WIFI? I've been using a Mobley hotspot, and Unite Explore hotspot (swapping SIM as needed) with AT&T with no problems. $20 a month, and unlimited data. It's been nice since my phone doesn't have to rely on cell data, and passengers can use the link as well.

Not sure this has been noted here but [MENTION=4974080]marchnz[/MENTION] sig has a link to the full PX5 MTCD system schematic. So I will be using it to find the 5V line to power a fan.... Hope Marchnz doesn't mind me pointing this out...
[MTCD Android Head Units General] verkion:
I don't think an active fan is necessary with a large enough heatsink. I just checked thermals today and it's peaking out about 65C, which from what I understand is almost 25-30C below stock config without an external heatsink.
[MTCD Android Head Units General] joeherlev:
Please link me to a good cheaper DAB+ dongle with antenna?
[MTCD Android Head Units General] ArtfulCodger:
I'm in Australia and when the interior of the vehicle itself reaches 60+C (hopefully with no one in it) it can take a while for even the AC to cool it down especially a large SUV...so to try to alleviate any damage the heat might cause I'm going with a fan...I have several from lots of old PC builds so should be fine, EMI not withstanding...
[MTCD Android Head Units General] marchnz:
Remember, a fan will only cool down to ambient. A passive heatsink adequately sized should be sufficient, especially there's plenty of room in there. Cant hurt to add a fan, noting a fan makes up for the lack of 'passive' thermal sinking
[MTCD Android Head Units General] verkion:
Whew! Totally didn't realize where you were. Man...60C sounds horrid! In any case, IF you are not adverse to what is potentially a lot of extra work, you could use heatpipes between the stock PX5 (wimpy) heatsink and the back of the headunit which has a fairly chunky bit of aluminum. Then, you could put a fan external to the headunit, as bit/small as you want running as fast/slow as you want with a cheap adjustable DC-DC convertor. Trouble with this is, I'm not sure where to find heatpipes...and I had lots of old heatsinks lying around so I used those instead.

Honestly, if I wasn't so excited about putting the unit in my car and having it up and running, I probably would have figured out how to do that myself since it would be a much cleaner "build"/customization.

---------- Post added at 08:06 AM ---------- Previous post was at 07:54 AM ----------

Guess what I found on a quick eBay search? Flat Heat Pipe! http://www.ebay.com/itm/Large-Flat-...hash=item33d321e015:m:mf4LbpQOO0ECVWPlyq0c5og

And...it's an Australian seller too it looks like! I have no idea honestly, if there's room enough to bend it to the back of the case in your Head Unit. Looking at the pictures of my KLD headunit, it might be a bit tough. Could probably fit it with some slightly creative bending though! Again, annoying/quite a bit of work to do this mod as you should probably sand the inner surface nice and flat (if you attach it to the back). The alternative is to heat pipe to the side (which is a much easier path), but you'd have to put another heat sink on the outside (which I don't know if you have room for).
[MTCD Android Head Units General] typos1:
Most units have a back which is designed to be a heat sink so you could simply attach the pipe to the inside of the back of the unit.
[MTCD Android Head Units General] verkion:
Yep. For sure. Just have to bend it up/around/past the rear panel connectors. Again, sanding the cast surface flat would help heat transfer. It IS a big piece of metal on the back. Probably would make a pretty darn good heat sink. I'm not sure why they didn't do that to begin with. They saved what? Like a whole $1 or $2 in parts and maybe 30 seconds in labour? If it was designed with that in mind...maybe even less time!

Oh well.
[MTCD Android Head Units General] typos1:
The back IS a heat sink, thats why they designed it like that, they were just relying on the air inside heating it up, well some manufacturers like Klyde used a fan to extract the warm air.

Hi guys,

I bought Touch Panel for my Unit:

https://www.amazon.de/gp/product/B01LQADPFO/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1

But it dont work on the Tocuhscreen. On Smartphone and Tablet everything ist fine. Ist it a capacitive Tocu screen? Then every Pen should work, no?!

Or maybe the Foil, that I put on the Display disturb the pen?! But its extra Foil for Tablets with capacitive Touchscreen. Im bit confused now.
[MTCD Android Head Units General] verkion:
I thought all the PX5 units by now used capacitive displays. Does your unit support multitouch input? If it does (past two touch points), it probably is capacitive and not resistive. The pens should work without a problem on the capacitive screens. Like you say though, could it be the protector you are using on the head unit?

Where did you find a film protector for your unit anyways? I've been looking for one for my 10.2" unit and I haven't found any yet.
[MTCD Android Head Units General] BobbyZee1712:
Yes, Multitouch works. I can zoom in and out in gmaps.

Its not a film protector specially for this Unit, I just bought a 12" one for Tablets and cut 3 pieces out of it.

When the pen works without the protector, then it would be fine too. The I wouldn't have fingerprint on the Screen anyway. Maybe I have just to care more when I clean the Display?! Don't know how sensitive the Display is against scratches...Bit afraid of it *g*
