I have a 2007 525xi. Ihave paired two phone to it- Blackberry 8820 and LG NV. I was told that the first phone that you pair was teh default phone and the car would search for that one first. The Blackberry was paired first. However when both phones get in at the same time, 3/4 of the time it pairs up with the NV. Is there a way to make sure it checks for the Blackberry first?
Thanks
