[MTCD  Android Head Units Q&A] s.rahus:
Hey mate, so the technical support at Bonroad believes that I have fried my Radio IC and that has to be changed. They are ready to ship a new Radio IC /Chip free of cost if I can get it fixed/soldered after removing my current fried one. The other option is to send the unit back to China (the shipping itself is too costly- I'm from India) and then they will send a replacement. Have you ever replaced the radio IC, is it a big deal? I mean, I am no expert with this stuff but I can find people who can do it. Bonroad will still honor the warranty even if I open up the unit as this is suggested by them. What do you guys suggest? I don't mind to go with the repair though its not even 1 week old, I just don't want my car to go into flames because of a bad job :) .

Thanks in advance!

Cheers,

[MTCD  Android Head Units Q&A] typos1:
There are lots of pins on the radio IC so it will be hard to do it yourself unless you can get something that will heat up all pins at the same time. another option might be to remove the SoM (processor board), dismantle the unit (just approx 15 screws, not that hard) and send the mother board off to be replaced, which would be cheaper than sending the whole unit.

What is it again that makes them think youve fried the radio IC ?
[MTCD  Android Head Units Q&A] s.rahus:
I can find experts here who can replace the IC for me, I am not going to do that myself :D. The seller said that he can ship me the IC (easier than sending the motherboard back).

The issue is this- [youtube]bIAUGKulZi8[/youtube]

Mine is a 2016 VW which has this quadlock connector. When I initially connected the connector to the socket provided by the seller I observed that it was not 100 % aligned on one side. But then I thought its okay as the HU booted up and everything was working including the radio. However after an hour or so when I tried the radio it was not capturing any signals, there was an absolute silence, no FM hissing sound even. So I removed the antenna socket from HU and accidentally it touched the body of the HU and there was a spark. Now I started to become suspicious. I removed the quadlock connector again and used more force and connected it to the connector provided by the seller. This time it was aligned 100 % and there was no spark even when I touched the antenna socket to the HU body. Also, previously the HU would not boot up if the antenna was disconnected, but ever since I align the quadlock connector properly it boots up the unit even without antenna. I guess, the improper connection resulted in no grounding and the current was passed through the radio chip and it fried it. Of course I did not explain this to the Bonroad support, but based on the current behavior they too suspect that its a fried Radio IC.

Have a look at the video and please let me know if you have any suggestions.

PS: Playing music via USB is working. And I can hear the touch sounds and Bluetooth calls, etc. Navigation too is working.

Do you think I should ask for the entire motherboard rather than just the radio chip? How costly is the board? Any link for reference?

Cheers,

[MTCD  Android Head Units Q&A] typos1:
Hmm, ok, yeah t does seem like its dead.
[MTCD  Android Head Units Q&A] zerozoneice:
didn't try to replace the radio IC and never will :) i let others solder, who know what they're doing...lots of things can go wrong, destroying circuit paths which have to be reconstructed...and the chinese solder paste is a b**ch to melt & remove, much more subborn than european one. apparently different composition used.
[MTCD  Android Head Units Q&A] s.rahus:
Yeah! If I am going that path, I will give it to experts, also the seller has confirmed that even after changing the IC if the radio is not working, they will replace the unit or refund.

Now I also doubt the antenna adapter. Please have a look at the attached photo. What is that rectangular black box (highlighted in read)? Why is there a green wire to which we are connecting the ANT wire from the RCA out? If that this is broken it will have similar behavior? [I know that you have already told me that its "an amplified and powered antenna", my question is that so if that is broken then the radio would not work, right? Can have the same behavior, right?]

[MTCD  Android Head Units Q&A] typos1:
You just need a 300 deg solder iron, I bought one the other day from Lidl with a useful thing that holds the solder near the tip, no more needing 3 hands !

I ve borrowed one that heats to 300 deg in the past, soldering is pretty easy, the problem with a larger component like the radio IC is that you need something that will heat up all the pins at once - there are like 10x3cm of pins from the radio IC that are soldered through the board :eek:

i managed to get a ROM for rk3188 px3, Android 7.1.2 build 20170721.

will share link once i manage to dload it.

---------- Post added at 12:15 PM ---------- Previous post was at 12:13 PM ----------

yea, it has no booster because the VAG OEM HUs send 12V up the antenna properly.

3rd party ones do not, that's why we need to inject 12V somehow into it. The antenna amplifier is actually on top of the car and needs 12V to "turn on"
[MTCD  Android Head Units Q&A] typos1:
Cool.

So the seller sent me the photo of the Radio IC to be replaced. The IC is actually in a casing that is soldered to the motherboard via 10 pins- have a look at the attached photo. Looks not that difficult to me (anyway I will give it to the experts to do this job). What say, you guys?

Can it be intalled on unit with android 5.1 ?

How did you install it via recovery or bootable sd card?
[MTCD  Android Head Units Q&A] typos1:
Yes, I know, thats why I said that you need some sort of plate attachment to the soldering iron to heat up all the pins at once, you cant do it with a point on the end because by the time you have moved the point to the next pin the previous one has cooled
