Travis could not get the contact us to work on your web site so here, Got my truck in JAN, with factory 1-button remote start. Don't like extra FOB, limited run time etc. In others I have installed used the 3 unlock pulses to start. Is there a system that will 1) run 20 min or so, 2) 1 FOB 3) allow me to turn on the rear window and mirror defrosters (CAN Bus??). Don't know if the 1 button system used a transponder bypass or some other device but I'd like to reuse if possible. Is something like this available and what would it cost for the pre-wired version. Thanks in advance for your time. E-mail me directly. cpfixer@yahoo.com
