Smart choice. I bought my 2005 a few years ago. It was equipped with an after-market Clifford remote start. I didn’t receive ANY instructions or information on it when I got the car. Just an extra remote key. I studied everything I could find on the system. I followed all of the instructions. And when I tried to implement the remote start, I ended up with every warning light lit upon my dashboard. It took a while to clear everything back to normal. I put that remote away and vowed to never touch it again. I’d like to remove that system, but that’s another headache I don’t need.
