Subject: low in-call volume since installing TV module Author: bimmerz5 : 83 posts Posted on: 2008-02-19 21:07:33

i don't know if this is a problem with the TV module or the bluetooth module. Here is the setup:

2003 E39 530i. Did a virgin widescreen nav install early 2007 with the retrofit harness. Uses BM53 radio, MK4 nav, and MP3 CDC. Everything worked at this point, including the BT module w/ my Verizon Razr phone.

Then, late last year, I bought a TV module, created a harness for it but it didn't work because the wiring diagram i used was for pre-2002. Then I got really busy and didn't have time to figure it out so I recently bought the correct harness from bimmernav.

I installed the new TV harness and now TV works great and so does everything else, EXCEPT the in-call volume when using the BT module is REALLY, REALLY low. This was never a problem prior to installing the TV harness. Is the low volume in the BT module related to my TV harness install or is my BT module beginning to fail on it's own for unrelated reasons???

any help would be appreciated ... thanks!!
