08 trailblazer bypass recommendations

Hi guys. I'm thinking about installing a r/s on the wifes truck. I just wanted to see what you guys might recommend as far as the bypass module. I know there are a few to choose from. I'm not sure what system I will be using but it will most likely be a dei product. I hear people saying with certain bypass module the newer gm vehicles are fairly easy. Just wanted to get some tips from the pros. Thank you. Any help is greatly appriceated.

A GMDLBP is very similar to the 1700G and gives you lock/unlock/disarm/passlock bypass all in one thru 1 wire. I use them on every Trailblazer/Envoy I do. No flaws whatsoever.

The 1700G will do locks as well. But i just looked and its been discontinued. Ive used the 1701G worked good for me. Same as 1700 just newer. Gets the data through one wire at the obd plugIf i Can't Install it    I Don't need it   Joe

XK01 comes preloaded with AMDL firmware that will do everything the GMDL-BP or 1700G will do, plus window rollup on all 4 windows with a second press of the lock button. Manufacture is xpresskit.com I have used this bypass many times on this car, works great. BTW, the brown 2nd accessory needs to be powered up on a 08 Trailblazer, so you will need a relay.
