Nearly impossible. Today I disassembled everything and there is a single PCB with all the buttons, for radio and navigation behind the panel. The only solution would be to relocate the headunit with the PCB and use the lower part of an another one connected only for illumination and controls of the nav part. Not worth it. (At the moment
)
A lot of effort from Honda to put everythyng together and still make it full of flaws.
The list of things that really annoy me:
-RDS not functioning properly
-MP3 folders taking ages to read
-rubbish sound, despite the infinitys
-unable to dial from the mobile to transfer to
HFT
-no nav coverage for my country
So, I will install a Blaupunkt amplifier and Parrot ck3000 evolution BT kit instead of OEM. Hope I will be able to use the OEM wiring for muting and sound input. Will keep you posted.
