Where to Mount GPS Antenna

Hey all, I've ordered the Pioneer GPS adapter (AVIC-U260) for my head unit and was wondering where others have mounted an aftermarket GPS antenna? My truck came with the base sound system so I'm pretty sure there's no factory antenna installed. Any suggestions would be appreciated. Thanks!

 

People have mounted it under the dash without any problems, and some have even put the antenna right on top of the headunit. The important thing is to not have any metal above the antenna as that can block the GPS signal.

Thanks for the links, chenbro! Consensus seems to be under the dash.

 

I did my install this weekend. Just above the glove box is an air duct that's flat on top and about 2-3 inched below the dash pad. The GPS antenna fit perfectly on it and is working great.

 

I mounted mine on top of the head unit.
