Have searched and did not find this addressed: I am unable to pair my i760 with my auto's built in bluetooth (2008 MB C350). I had no problem with 6.0 version. Now after successful upgrade to 6.1, car and phone see each other, but when I enter the code on my phone to pair (using same numerical code 0000 that I have entered on my car) I get a message saying connection failed. Any ideas?
