I have a new F900BT, the hardware bypass worked perfectly. I grounded both wires to the common radio ground (blk) with no issues. Thanks!
One question I have to ask: When a route is "live" on the GPS, the Audio on the XM and IPOD take hits or breaks up a bit. Feels like it's related to the GPS because when I delete the current route, it stops. I have both the Master and voice volume off or all the way down. Just wondering if there is a work around so that I can use the GPS and listen to music with out the GPS audio/speach. -I coulnd't find a related post.
