2005 Buick Rendezvous CX AWD 4dr SUV (3.4L 6cyl 4A)
The one item that I have a concern is I cannot use my lighter to charge my cell phone as it blows the fuse. I was told to get an adapter and put it in before I use the charger for my cell phone. I have friends who have the same SUV, not the Ultra and they have no problems.
OnStar and satellite radio.
None at this time, unless the cig. lighter can be improved.
