I am thinking of adding the pioneer XM Radio unit to my H2. I was wondering if anyone else has done this? My wife has XM in her Denali and we love it and was very dissapointed when the H2 didn't have it. Anyway the other question I had was. Would I have to have another antenae(spelling?) on my vehicle or could I use the onstar one already mounted on the H2, reason I ask is the antenae's look the same. Any help would be appreciated, also if anyone has replaced the head unit with a pop out lcd screen please let me know.
Thanks
