One that I found is Pandora security system. They claim the engine remote start feature on some of their products. I did not find however any info about whether it applies only to cars with an already preinstalled remote start unit (e.g. only Mustangs with an AT), or could be used also on cars with the manual. Does anybody know?There are aftermarket solutions, though. They're not as nice as an integrated OEM implementation, but still better than nothing, I guess.
