CN03-03101B-US-A head unit won`t turn on

[cyberkul]

I notice that you (Jammy) linked to a new DAB-app in another post: https://mega.nz/#!tFsWVYST!II9_kXdPIgh4 ... a6MOAisZ2E
Will this work in my HU? Any suggestions regarding the cold boot issue?

Hm.. this file (dmcu.img) is only 168kb. Is this the correct file?

Hi,
yes. MCU files usually be a little memory files.

Unfortunately, still cold boots. I also uninstalled and reinstalled the DAB+ app. I don`t know if it is the same version. Don`t know yet if it works, just tried it for a few minutes.

The DAB+ is also the same. During a 10 minutes drive this morning I had to restart the app 3 times.

Hi,
sorry,one of our client said that this MCU can solve the cold boot problem of the unit.
So i send it to you.I know ,it takes a long time to solve this problem.However ,we test the same unit but don't find the problem.
Regarding the cold problerm,if you don't want to wait more, you can contact the customer service where you bought the unit to return the unit directly to China for repairing or just change one and so on.
Hope your kind understanding.
Regarding the problem of the DAB,you can try to install this one.

Thanks! I`ll try the DAB-app. Regarding the cold boot problem, I have already changed the main board. The cold boot problem is the same with both mainboards, but my canbus-problem was solved with the new board.

No, it didn`t help to install the newr DAB+ app. The app still hangs. Sometimes it works for a long time, other times I have to kill and restart the app several times even for short trips. VERY ANNOYING!
