I've pondered the same question myself. Now... the radio is capable of supporting an AUX in, and you're able to purchase a BT interface for it from Australia, same guys that sell the OEM or JHP gauge pods. Also, numerous MFG's sell VW interfaces. I haven't had a chance to try this, but you can get a VW Aux in plug, which came with older Blaupunkt radio's. Scosche and a handful of other Harness suppliers sell these, and they are very cheap $5-$10. I'd be willing to help take it apart and try it out. I'm suspecting that the radio will simply switch to Aux when it senses voltage coming in from the aux plug.... but then again, this is merely a strong suspicion of mine, not grounded on any concrete fact or previous attempt.
