I have the new edge with attitude on mine and i had a problem with my older unit and it didnt have the turbo timer and when i called edge they said we will send you out an up dated new version and it had the turbo timer in it at no extra charge and its great just get out of the truck and take your keys with you. No waiting to let the turbo cool down.

 

tst 49 hear works every time on my 03, it's amazing how long it takes in the warmer weather to cool down.

 

I need to find something that works, that wont void warrenty. I get some funny looks from co-workers when they see me sitting in my truck in the morning letting my truck cool off. I just tell them I am decieding weither I should go into work, or drive home.
