I have upgraded RT4 from 7.11 to 8.11, the whole instalation was sucesfull,everything works except the audio - no radio, no navigation sound, nothing. I tried also 8.20 with same result, everything works again except the audio. The sound system is JBL. Is there any set up I have to do and enable the audio using peugeot planet? or can anyone share firmware 7.11 so I can downgrade it back?
I tried that, I used mirascrit to change the audio section in RTxSet, but no luck...I enabled AUX and I will try external device to play sound in my car. I belive this will work, it has something to do with audio setting of RT4
