Had a Verizon bb 7xxx and the address book wouldn’t work with my 06 A4. Tmobile came out with the new 8700 and same issue.

Took my car in for the 5K check up and they changed the software on the car and now the T-Mobile 8700 works flawless.

Just a heads up for any fellow A4 (perhaps other Audis?) owners.
