My husband purchased a remote start for my new Wrangler here. My experience with the staff was excellent. My remote start is excellent, and the cost was very reasonable. They talked to me about the differences between using my vehicle remote or a separate fob. I chose the separate fob, as they said the range would probably be greater. So far, I'm extremely satisfied with the product.
I will have them look at installing an auxiliary cable on my 2001 BMW radio in the spring when I take it out of storage. (That series radio does not have an auxiliary port in the back of the radio, so it is trickier.)
I'll update after my radio is updated.
