remote start/keyless entry, 2007 sierra

there is no note to indicate so on the instructions, but there hooked up very similar not exactly the same...so i would have to say quite possibly yes..

It shows on the Bypass kit website the 1701g does the transponder for the new GMC trucks.. Is that correct?????

That's correct, the 1701G will do immobilizer bypass and a bunch of other things. It doesn't handle the multiplex resistance wire at the ignition switch, so you'd possibly need to wire a relay/resistor to handle that.C Renner's Auto Electronix

My service is cheap, quick, and good - pick any two

ive done quite a few of these trucks and unless its a fully loaded unit with factory remote start, there are neg door lock wires (pink/blk and org/blk)at the bcm or in the left side of dash panel, also dr door trigger is there, pass door trigger is behind pass side of dash side panel, neg park lites at switch, ign, acc at switch, power at back of fusebox, if your system (as the audiovox does) powers the ign acc circuits in the proper sequence,(acc,ign,acc drops) the mux circuit isnt required i do at leasst 5 chevys a week and have NEVER tied into the mux circuit,and i just program a blank key from howard keys and place it in an astcbm(coffin box)
