I Like Teh Boom
I only have the regular 791xv, but I would highly recommend the backup battery, the glass break sensor, and a couple of extra sirens, one in the engine bay and one under the dash. I paid $250 to get my alarm installed with all the bells and whistles (including remote start //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif ). Looking back on it though, I should have installed it myself, just didn't have the knowledge at the time. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
