Installing a viper 791vx in an 05 Denali, I bought a 457gw with the RS. Is this the best module to use for this application?

I thought the 791xv came with the remote start?

it does; the 457GW is the databus interface for doorlocks, and bypassing the passlock

Okay... first of all, hi everybody! I started using the 457gw last summer wid viper rs 160, 771 an 791, at least once a week. Never heard any complaints from customers... seemed everything works for them. Then I get an 03 tahoe and think "no problem" done a lot of em, right? WRONG!!! first, the heated seat thing (read that-makes sense) but then, the perimeter lighting and the lock/unlock wouldn't work. Disarm would chirp but no unlock, arm would chirp but no lock. It seemed to stop messing up except for the perimeter lights, so i left it alone. Now, the locks only work with the factory remote and if u try to remote start it, the factory alarm goes off. WTF? Can anyone explain this? I've done the exact same install on 02-05 tahoe, 03 silverado ss, 03-04 escalades, and now it only messes up in my own friggin car?!

DEI tech support waS right as far as the heated seats and front defroster coming on if the temp is really low, thats all... as far as my other concerns, they pretty much gave me the run around... but like i said, never had any probs wid 457gw til i put it in my own tahoe i did an 04 yukon and it was fine, or at least i haven't seen the customer since i put it in about 2 months ago; put one in my friends 04 z71 tahoe and his works fine, so you can see why im a little upset that its messed up in my own car
