hi guys:

Finally the 2nd technician was able to put back the 4 pins into their respective places and put them back into the 40pin harness. After which, he put the old stereo back and the radio is now running.

Upon putting the hualingan harness into the BMW harness. No sound came out of the radio. What he did was , on the hualingan harness, there are 4 loose colored cables. He put two of those cables into different pins. I believe one of those is for the radio and another for the wheel steering. Finally there is sound in my radio. I also tried the stereo control in the wheel steering and its working perfectly. Upon pairing my phone, the phone bluetooth is working as well as the other party can hear me loudly ( and vice versa).

a. What need to be done on the other 2 loose colored cable that comes in Hualingan harness? Are they of any use? Where should i put them?

b. Things that are not working

1. iPod - once iPod is connected, it can show my iPod playlists and once I click on a song, screen will show and running, but no sounds coming out of the speaker/s.

2. CD - once I put the CD, it can read the CD and track is running and seconds are counting( and i didnt put in mute), but no sounds coming out as well.

The tech said all his electrical wiring are correct, bec if not, there will be no radio sounds and phone bluetooth sounds. What do you guys think the problem is?

3. TV - there is a TV antenna plug on the stereo ( besides the iPod connector plug) but no cable/ plug etc that comes with the packaged. What do I need to buy to make the TV run. What else need to be done.

4. NAV - not sure how to make it run.

Thanks,
