I have an 07 H3 with the standard 1 disc cd stereo with XM. Does anyone know if there is an auxiliary plug on the stereo? I would like to plug my portable gps in if possible so I can hear it through the car speakers. Also, where would you suggest I hard wire the power cable? I'd love to hear suggestions! Thanks...

Best bet is to add a small 3-4" flush mount speaker somewhere and take power from the cigar lighter socket. Even with the new GM "Black-Tie" radios with aux input (not yet on Hummer) there is no way for the system to automatically select the aux input whenever the GPS unit needs to issue a command.

If you want totally integrated navigation, simply subscribe to OnStar's directions plan. It works great.
