I have a really odd problem, I installed an EVO-ALL with GMT4 T-harness in a 2010 Tahoe and added a RF642W remote kit. I can start the vehicle with 3X Lock, but not with the RF642W. I have the RF kit option H2 selected, I got the visual on the EVO-ALL and the blue blinking light on the RF antenna that my remotes got paired with the EVO-ALL, but they still do not work. just for the heck of it I changed it to option H1 and was able to start the vehicle with the lock button on the RF642W, but was unable to shut the vehicle back off. I am not sure why I can not get any reaction from the my RF642W remote with the option H2 selected. Also, this vehicle also had a factory remote start installed, I douibt that has anything to do with it but just thought I would let you know. Any ideas?
