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"

I solved the problem by myself.
Downgrade of the MCU firmware to V2.41_1 did the trick.

The update provided to me by jammy did not fix the issue.

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.
