Great - thanks for the info!

I'm thinking about getting one of these:

This is a Bluetooth upgrade module that fits into the CPT9000 cradle and allows a Bluetooth phone to work the same was as the CPT9000 phone would work, including steering wheel buttons, phone book, etc.

This looks like an easy way to get bluetooth. This is only $200 or so, instead of triple that for the new ULF module setup in the trunk.

I am still doing some research, but I will probably see if I can get one of these...
