I have a successfully working install for 2014 Chevy Trax with T harness. Current firmware updated and used the flash updater to customize for the specific car. Enabled the 3 lock button press OEM remote start option in the menu, saved those settings to the unit. Followed the key on/off proceedures to program the unit successfully.
For some reason, it takes 4 lock button pushes to get the starter to engage. Sometimes it take 2 sequences of 4 button pushes also. So sorta scratching my head.
The unit is presently attached under the dash and I dont have the service number for the unit. If it's critical, I can ge the number however.
