can anyone please tell me about my head-unit, what i can and cant do with it and if its upgradable.
Audio sources d90-810
CPU CORTEX-A9 DUEL CORE
ANDROID VERSION 4.2.2
MCU VERSION 4.3.11-22-13-E50201
SYSTEM VERSION 2.9.3-20150115
I have fitted a USB DAB dongle and down loaded the YHX_DAB+20170328-zoulou-2017-04-09.apk its all installed but when i put the car into reverse it says no video signal
Any help will be very appreciated
I can tell by your MCU that you do not have an MTCB head unit, so youre in the wrong forum, try the Android Headunits General forum.
I can also tell you that the "no signal" message is likely to be referring to the lack of a signal from a reverse camera, not a DAB box.
