RK-A701

Hi everyone.

I have this unit. RK-A701.

I noticed the usual problems others have. Very poor wifi connectivity (disconnects randomly)

and bluetooth is poor.

I purchased this unit because of the bluetooth.

Does anyone know how to make it work reliably?

The sound cuts out and is garbled, the other party cannot understand me.

I tried connecting an external microphone above my head close to where I sit in the vehicle.

I connected it in the back on the MIC + and GND pins.

It hasn't helped.

Any help is greatly appreciated.

If I can't figure it out, I am going to have to sell the unit because I depend on the bluetooth 100% every day.

Of course I am getting ZERO support from the seller on ebay!!

RK-A701 Bluetooth and wifi issues

I installed an external wifi antenna seem to help the wifi a little bit.

I just soldered an sma connector to the existing on board imprint.

Mounted the connector on the back of the unit and I use a magnetic antenna on the roof.

It doesn't work very well unless the antenna is on the roof.

Bluetooth is really bad no matter what. Must be a hardware issue.

Getting INSERT iGo SD card message

Hi if you can assist me I would appreciate it.

I got mine from ebay has no sd cards installed and getting the error message insert iGo SD card.

I downloaded the apk file and installed files.

I can see the satellites but try as I can cannot make the iGo work.

Supplier in broken English not much help.

Does the unit require 2 sd cards in it Left and right (the one marked maps? and one marked GPS)

I can see 24 mbyte file in file explorer but cant make the gps work.

So as you said you pointed yours in settings to Google maps.

Any help to get ths working would be appreciated.

Also how to get that bright circle to disappear off screen too.

you can email me if want vk3zaz at gmail dot com tnx for looking.
[MTCB Android Head Units Q&A] Chewi3:
Hi steve_gee

I never managed to get iGo working. I installed Here WeGo app which (despite the odd name) works well. Allows for easy downloading of maps for working offline. Another user here has found that OSMAnd works best for them so may be worth a try.

The unit does not require the sdcards to be in place (although iGo might..) as I have used it for some time without them.

The bright circle can be removed through the settings menu (if it asks for a password use 66668888). Can't remember the exact name of the setting off the top of my head, but if you can't find it let me know and I will look on mine.

Have anyone else problem with back 4-pin usb? Is any configuration needed? :confused:

I also would like to ask if there is any way to record video using front camera, AV/RCA not USB... :fingers-crossed:

Unfortunately as I saw, bluetooth device of RK-A701 appeared to be a Hands-free/Carkit device!

It can be used only for voice/sound transfer and nothing else.

I tried 3 different USB Bluetooth dongles, but android cannot recognize these.

If anyone wants to connect OBD interface, he can use USB OBD ELM327 that works perfectly with DashCommand app!

I traveled with this type of navigation few hundreds of miles on a familiar route, but I was disapointed with his very Poor radio reception. When I traveled on the same route with my old VW radio system, with the AF set on RDS, I was able to listen a national Radio without any problem even if the radio broadcasted was changing the frequency in the nearest city.

In the current Android Navi I let the AF on, but the signal let me down a couple of miles away from the city and it wasn't able to switch to the next frequency of my favourite Radio Station.

Q: IS IT POSSIBLE TO CHANGE SOMETHING FOR THAT? Can I improve the radio reception or to swich from frequencies of the same RDS Radio Station? I've done something wrong? I must enable/disable another RDS option from the Menu?

Or it is a simple hardware limitation and I have to take it just as it is?

Quite late to this party. Just fitted one of these appears to be running 5.1. Has Igo installed and have a spare 16gb micro sd. Have downloaded IGO maps q4 2016 and put all the folders in the download onto an SD card. When I put the card in the map slot and start IGO its like it doesnt see the maps. Have tried to download sygic map via aptoide and that also dont work just sits at 100% and doesnt install. Missus needs to use car tomorrow and is going to have the hump as I have took the old windows CE sat nav out. Also dont seem to be getting the full storage amount only got 645mb free but when I got to file manger it shoes 11GB free. Any help much appreciated.
[MTCB Android Head Units Q&A] nanu_mihai:
You must move the MAP folder with your new maps from micro-SD card to the iGO folder on the internal memory. The iGO folder has “content” folder and there is the “map” folder. Delete the map folder with older maps and just move the map folder from your micro-SD to that location.
[MTCB Android Head Units Q&A] scoobydo123:
So I am using file manager but cannot find the igo folder! Just downloading over wifi IGO from aptoide this is a 346m file not sure if I have enough room on the device as I can access all the storage. The move to SD card option is also greyed out. What am I doing wrong. Thanks
[MTCB Android Head Units Q&A] nanu_mihai:
With ESF File manager you’ll manage to get it. On internal storage.
[MTCB Android Head Units Q&A] scoobydo123:
Using the file manager that is on there no dice so will get the other file manager. But would like to put on external. Strange thing is have tried on an Android tv box running 4.4 and have got a version of Sygic with a UK map and I could do that fine. When I install the app I get a choice of internal or external and it installed fine and maps is there obviously no GPS on the TV box. On the RK-A701 it just comes up with detecting country and I get no further. Is it because the device is rooted? Thanks

Can anyone give me better pin out instructions than the sticker on the unit

Hi can any one please give a better explanation to me for 13 threw 19

for example mine says

18 r-cam

19 brake

I think they are both 12v + but I don't know. I guess one is brake light safety trigger and the other is 12v + OUT to the rear cam

I was going to hook 18 to the ACC wire. Am I on the right track ?
[MTCB Android Head Units Q&A] MoshPuiu:
18-> +12Vcc from reverse lights (or backup lights). On activation it will switch automatically the screen to video input R-CAM (RCA side).

19-> +12Vcc from brake circuit. It is used for safety regarding watch movies during driving. It will be use according the settings. So, when you want to watch movie clips you must pull up the hand brake to be sure the vehicle is not moving.

20-> +12Vcc to antenna amplifier unit (if the car is equipped with it).

I don't know how they can sell this junk!!

This unit doesn't work for wifi and bluetooth phone calls. It's useless.

I guess that is why the cost is $200 instead of $600.

Look at this thread. There is a russian link somewhere in the thread with some good information. This will only give you some ideas, it's NOT THE SAME BOARD!

I am going to try this on my RK-A701.

Be CAREFUL!! Every single board is different. There are many Chinese boards with different tracks. You can very easily render your board useless and ready for the garbage can!

I have already connected an external mic to the two rear pins MIC + & MIC-. Bluetooth is unusable! The other person cannot understand me on the phone.

I am going to try to disconnect the internal mic circuit from the bluetooth module.

I will post my results here along with some pictures in the next few days.

Yeah but BT does work for calls and audio streaming, but i cant connect the unit with OBD2 dongle for example, thats what im trying to say.. Maybe if i could somehow remove the integrated bluetooth module and replace with another one that would actually work for connecting to devices other than phones and work as BT is supposes to work?
[MTCB Android Head Units Q&A] ckeays:
RK-A701 Bluetooth issues

I also tried the OBD2 dongle. You are right it doesn't work. I don''t think it's a hardware issue.

I think it is a software issue.

I doubt anything will change since there are no custom roms for this unit.

I did remove the microphone from the board, and it made a significant improvement with bluetooth calls.

(now the caller can hear me and understand me)

As far as cutting tracks on this board, I would be very careful!

I am sure there is room for improvement if I connect a better quality external microphone.

Hi all.

I need help with my RK-A701.

My unit was stock I had not done anything to it - a few weeks ago it lost audio playing music in all speakers except the right front.

The radio still worked with all speakers but music only played thru the front right hand speaker.

I fixed it by running restore factor settings - a few days later it did the same thing.

However this time when I attempted the restore factory settings it stalled and sat on that screen for ages until I reset the unit (about 10 minutes)

When I started it back up it would reset itself every time it got to the main screen - however if I quickly started playing music it wouldn't reset.

I again tried to do a restore factory reset which stopped the unit from resetting but didn't fix the audio.

Now the unit has no audio at all and the screen flashes on and off every 3 to 4 seconds - very annoying....

I searched around on the internet looking for an answers and found the Russian site...

I try the update but it doesn't work - it copies the file ok - but then after reboot it stays at 0%

I've tried several different USB drives - none seem to make any difference.

At this point I'm guessing the boot loader in the unit is corrupt.

What can I do to restore this unit to working again?

I notice that the unit does have an OTG port that I can wire up to flash the unit but no one seems to know anything about these units...

Up until this happened I loved this unit - it has everything I wanted - I really don't want to have to buy another one.

Any help would really be appreciated....

Thanks.

Hi everybody.

I failed to resurrect my rk-a701 unit with Android 5.1, purchased a year ago, which I had crashed doing "bad experiments".

So, even to not change the wires in the car, I bought another one.

With surprise, I received a car radio that, compared to the previous one, has only the name (RK-A701)

This unit has different engineering components (see photo).

It is also bad as software with android kitkat, bad bluetooth (the phone is disconnected continuously), slower, and little powerful wifi.

The version is: k6_01_LH_V2.0.1_20180323

Someone, in the hope of a performance improvement, has some info to update it to 5.1?

With such different hardware I'm careful to try to upgrade to 5.1 with the available roms for the old model.

Thanks in advance.
