I have a 2008 GP and was looking to have a security & remote start system installed. I went to the local guy here and according to my wants/needs he suggested the Avital 5303. He stated that he had everything he needed and quoted me a great price for everything. First day he said the "brain" on the system was bad and that a special one programed just for my car had to be ordered. Ok no problem i said. The next day i call and he said he is finishing up the last couple things to button it up... I said ok cool. I got dropped of down there only for him to say he had to remove the system because my dash gauges were jumping all over and etc. He said that the Avital system i wanted wasn't compatible with the a certain year range of GP's... i found this to be surprising.

Has anyone installed a 5303 or know anyone who has installed one on their GP?

He did state that for all the trouble... he will find an equal replacement or better to install at the quoted price.

Thoughts?
