Update on this.. X just got back from the dealer on friday. they had it for a month.. they didnt fix the reverse audio channels on aux 1 and aux 3 through car speakers ,or fix the impedance mismatch/ overdriven output signal, but they did put in 2 new monitors, so they fixed the remote issue. and put new ground filter in and new aux cable in and got a new game controller. Looks like Im a trace these wires out in the in connector and reverse them or trace them out to the back of the mid/cd player and reverse them. Left to right and add some more 10 k resistors to the dvd ouptut signal. it was funny the new monitors didnt come with aux 3 enabled and they called me asking me how to enable it and told me that in 2007 bmw canabalized the plug and stop making aux 3... BS... hold down menu button for 8 seconds hidden menu comes up. enable aux 3.
