Hey Guys I am new to the forums. I just bought a 2007 H3 Base. I was wondering could I buy http://cgi.ebay.com/ebaymotors/HUMME...ht_1056wt_1057 This and call a local place and get them to install it? Is that possible?

 

the listing ended so i cant see what type of mirror your looking at ive picked up all the parts to do this for myself just havent gotten the time yet mines a 08 H3X Alpha and so far with what ive been able to figure out on mine the harness at the mirror (has temp, compass,auto dimming and onstar ) all the wiring is there except for the video input to the mirror (it does have the reverse power lead to power the display already installed ) which means im left with running wires up to the new display mirror (mirror is supposed to be a direct gm replacement with all the options and onstar ) and a harness back to the cam ive still gotta install (mine recommends using the reverse lead from the trailer plug to power the cam ) im hoping to maybe start this weekend
