I am looking for an alarm/remote start combo since I am going to have to commute everyday to my clinical for school early in the morning and I don't wanna freeze. I was looking at the Viper 790vx, Audiovox Prestige aps996 and aps997 and the compustar 2wfm-s. It is safe to install the Viper and Prestige on a manual cuz I can't find anything saying no, but I know the compustar has a different specific brain for the manual. If you have any of these can you give some feedback.
