Does anyone know how to adjust the RUN TIME of the MOPAR Remote start. I have read that the dealer has to do it? Is this true? or is there someway to do it yourself? Its cold here in Maine and it doesnt seem to run long enough to warm up the car in the mornings! The max 15 minute run time would be great! Any helps is greatly appreciated!
