Greetings from the UK !
I know a little late, but just bought the 900BT and fittng it tomorow.
I have read all through this hack, and as above, picked us some good instructions.
I have prepared the wiring loom for the unit following the hack - grounding the moved mute cable, along withthe handbrake cable so all should be good!
BUT ! I have never switched this unit on before and its brand new. I have read mention of a "reset required", since its new - will it need one, and if so how do I do it?
many thanks to all those who have contributed to this thread so far
Jon
