car electronic problems

[fsunole]

I bought a 2004 camry recently and it came wit a sirus satellite system, navigation system, and dvd with two screens in the head rests.

Problem 1: The antenna for the satellite system was not mounted so Toyota remounted it. Ever since they remounted it, the system says that there is signal problem.

Problem 2: The car's battery died after I purchased it and Toyota installed a new battery. Ever since they did that, the navigation system will not turn on and the dvd player will not turn on as well. I confronted Toyota and they said that I must have blewn a fuse when I tried to jump the car.

Toyota refuses to fix anything since the equipment was installed by the previous owner. So now Im looking for a business that can fix all of these problems.

Have any advice what might be wrong, is it an easy fix that I could do, or do you know a company that could? Do you think it will be an expensive fix? Does Best Buy or Circuit City do repairs like this?
