I have a New OEM VW Ipod Adapter for sale. Part# 1K0051510A or 1K0 0515 10A This was sold as an option with the MKV. It only was taken out of the box to be tested. I decided after buying it that I wanted to upgrade and get the Navigational Tuner instead. ECS Tuning is selling it for $225 plus shipping.
IPod Adapter Premium 7 plus (Satelllite Radio equipped vehicles only)
Comes with iPod adapter, iPod plug, Interface wire harness and instructions
The iPod Satellite Adapter is a VW part that piggybacks on the satellite radio signal and does not remove any external CD changer, sat radio, or aux-in. It only works with the premium 7 radio. It does work with the factory Volk-L bluetooth. It can show up to 250 playlists, and up to 16 characters of artist/song text info on the radio or instrument cluster multifunction display. It can also do song shuffle and scan. While using it, the iPod is locked and the sat radio is bypassed. The picture below shows what the screen looks like when using the iPod.
PM me if you have any questions.
