Does anyone know of a combo antenna that will work for both the D3 NAV and XM w or w/o traffic. I am putting this in a sedan and would like to have the antennas on the roof but preferably one antenna. Thanks.

After a bit of searching, I've come to the conclusion that the only multi-band (XM & GPS) antennas available are made for marine/aeronautical applications, and are rather large and unsightly.

FYI, you can mount the D3's GPS antenna inside the car, like up on the front of the dash or behind the rear view mirror, or even INSIDE the dashboard (if you do a search here you'll see what I mean), and still retain full function. That way, you only have the XM antenna to mount on the exterior.

Thanks. I saw those....pretty cool idea but not gonna fly on a sedan!! My other thought was getting an antenna cover painted to match the factory paint. I had an Accord that had one on the roof and I know a lot of BMW's do as well. Anythoughts on where I could find something like that generic or otherwise (07 Camry). I can't come up with anything.

Can't you just paint the actual antenna housing?

not a bad idea. just looking for something more factory to deter attention. Also, being stuborn about putting both on the roof. My wife's SUV gets a better signal than my buddies who put his in the Dash... Lame i know.
