hi. I recently upgraded my car, VW Eos 2010, radio to a JVC with apple play and BVT audio. I looked into a VW radio however was told by the mechanics that it wasn't possible to upgrade to a VW radio. So, I bought a JVC and had it installed....now, my compass wont calibrate. According to VW, the radio isn't compatible, however, when I purchased it, the specs did say it was compatible. Anyone else have any issues/luck/remedys? I really want my compass to stop changing directions, even when I'm stopped.
