If I do get one of those.......do you think it will void the warranty ??
No, unless the problem you're claiming on your warranty was actually damaged by the remote starter or the installer who did it. I did security and accessories for over 10 years, and I've had to fight these claims several times by dealers who told people that they were going to have to pay for repairs that should've been covered.
as long as you have someone that knows what they are doing when installing.
There's no possible way to stress this point enough. When dealing with things like security wiring,
ESPECIALLY a remote starter, the amount of liability involved is huge. We're talking about wiring into your ignition system, electrical system, brake triggers, and all kinds of electrical connections.
If you use a remote starter on a MT car, do you just not ever park with it in gear?
If you've ever seen a MT car with remote start try to start while it's in gear, then you'll understand the need for the correct product as well as a competent installer.
you'd have to bypass the cutoff switch that requires the clutch to be in to start the car, right?
Sure, or it just wouldn't start.
there are two different kind you can get....one for AT cars and the other for MT cars.....
I've always used Clifford for a MT, the same unit for both. It gets set up different at the install time for MT mode. I left the industry before Compustar got really big, so I don't know much about them.
