I have a double DIN install kit for a T7:

* Car stereo fascia - so you can put in any aftermarket double DIN and it will look tidy
* Steering wheel control wiring harness (including reverse sensor pass through) - so you can use the existing steering wheel controls on your new head unit. The reverse sensor beeps will also be fed through the new stereo
* Antenna adaptor so the pug antenna will work with an aftermarket stereo

Paid $430 at super cheap auto - make me an offer
