Not sure if this is in the right place but anyhow.

I have an F250 and I just removed the wiring and antenna from an old car phone. I now have 3/4" hole in the roof.

I want to install a roof mount GPS antenna for the 110BT and I am having trouble finding an aftermarket antenna that will A) work with the AVIC and plug that 3/4" hole.

Anyone know of any antennas out there that fit the bill?

Thanks

I've hacked up a GM onstar/XM/nav antenna before- bought one on eBay & spliced the cables. Worked like a champ... It required a pretty good sized hole, however, you just need to look to make sure whatever one you buy is close to the contours of your roof where the antenna mounts...
