CN03-04101H Fastboot issues

Postby advbug » Tue Aug 29, 2017 9:32 am

Hi,

I just got the CN03-04101H and I have problems with Fastboot not working. Its working for approx. 5 minutes after I stopped the car, after that the radio is completele rebooting.

I suspected the voltage not beeing there after this time, but I measured it after 30minutes and there was +12V on the radio and still it booted completely new.


I am running a firmware from 20170328. Mcu version is "V2.44_1"

Most people have the same issue. No fix from Pumpkin is available

I solved the problem by myself.

Downgrade of the MCU firmware to V2.41_1 did the trick.

First I had some other problems... If you are using a can box you should check if the wireing is correct for the ignition signal... My can box was faulty and only gave 7V out when ignition was on. So I just took the ignition signal from the cigarette lighter illumination. Works great.
