I talked to Onstar and they told me unless I paid for the service, it was completely unusable. I have (until Sep. 25) a trial period to use onstar and I have not once used it for a good reason. I have a cell phone and if I need directions, I will either use maps or call someone. If I am in an accident, we have a ton of cell phone commandos out there that will more than likely see me and call someone. As far as removing it, I would like to do that as well, 1) for more space and less battery drain and 2) I really don't like the idea of someone seeing where I am at or sharing information on my driving habits. I'm not going to pay $36 a month for something I have no reason to use. It's like paying for insurance the only difference is the law mandates that I pay for it and there are really more benefits to insurance than Onstar.
The main reason I posted this thread is to get exactly what I am looking for under the rear seat and what I need to disconnect to completely disable the Onstar system. Pictures would be great if someone has some floating around. Also, I am looking to find a NON-Onstar mirror with auto dimming, compass and thermometer. Is this possible to add to an LS?
