I was just at the local best buy, and was looking at the Viper 160XV. Just for the record, we do not want an aftermarket alarm system, just the remote start-keyless entry features like the Viper 160XV. The price at Best Buy was about $180, and I asked the clerk if it included installation. He said yes, but that for my 2000 teg, I would need an $85 (unit plus labor) 'bypass'. I was under the impression that I only needed that 'bypass' unit if I was installing an aftermarket alarm. Was he not listening to what I was looking at? Or do I need the bypass anyway?
