Have experience with BB 8700 and 8100 and two MB products.
05 G series with the puck - will only upload 99 entries from a motorola product (q phone) does not upload bb at all but can use the phone in simple bt mode and allows in and out calls and will begin and end with steering wheel
07 ML with MHI - 8700 uploads first 99 phone number and works perfectly as does the 8100.
