OK, this is driving me crazy. Everytime my Samsung Vibrant connects to my car stereo via bluetooth, it will download the phonebook. The reason is drives me nuts is it takes over the display of the car stereo saying "Downloading". It may take 15-40 minutes to complete.

I don't want it to download it at all! I will use the phone to dial anything.

Below are links to the phone, car stereo and bluetooth adaptor unit to help anyone solve this problem. Kenwood couldn't help.

The manual for the head unit, on page 24 simply says "
To cancel downloading of the phone book data. operate
the cell-phone"

Operating the cell phone in any way didn't appear to stop the downloading of the phonebook

It appears the profiles involved are:
OPP is a profile used to transfer data such as a phone book between units
PBAP (Phone book Access Profile)

Turning off Data Sync on the Vibrant didn't affect downloading.

In the Bt-300 bluetooth adaptor manual, I have what is designated a Model J headunit.

Please can somebody help with this, as this is hundreds of dollars of equipment that I can't use for it's intended purpose. Do I need to unlock/jailbreak the phone?
