Just got my new Crutchfield today and saw On Star is now something that can be purchased for any vehicle. Price is $299 and service ranges 19-30 a month. My question is has anyone actually messed with one yet like this. I'm wondering what install would entail and if too hard for a DIY who's authorized to install it?

 

I've been looking into this cause of the auto theft security thing on star has. The guy I spoke to said that on the truck I have it wouldn't effect anything in the console, but I would lose the ability to use my dome light.
