RS for Trailblazer & Silverado

[quote] The method I suggested does work. If you haven't done remote starter's before you're probably right in not attempting this. The module GMDL 4 rarely works when trying to do driver presets unless the installer knows a few tricks. [/quote] Car to share these tricks?? The GMDL4 defaults the truck to driver setting one. So does the 456G. What my shop charges for that vehicle: Basic starter: 200 Passlock II bypass: 50 If you want the 456G so your locks get controlled by our remote: 50 Total cost: $300 Our remote starts it, does locking, and both remotes control driver setting 1. If you don't want us to use the 456G to do locks, I charge you twenty bucks extra for having to go into the driver door to do disarm. It actually takes longer to do this truck without adding keyless then if you do add keyless. Total cost: $270 Our remote starts it, factory remote does locking and you retain your #1 and #2 settings.

I would definatly use an aftermarket system (not intergrate with the factory alarm, your still not protecting your investment) and use the 456G, that little baby will save so much time and money.
