I just got of the line with Kenwood Europe and apparently only two Nokia models are fully compatible with the 8220Bt viz N81-8Gb and 8800. The other models may sync the phonebook fully or may not and it has to be done manually. The SMS functions also work with the above two models as of now. Sony ericcson apparently, all the models are compatible and all functions work incl the SMS functions. Is this correct ? I am sure a lot of the DNX 7200 users must have also bought the KCA-BT200 modules ? What are your experiences with Nokia phones ?
