i'm in NJ so that's where I got it installed.
it depends upon the installer. I spoke to an installer at best buy who knew how to do it, and most of the private installation shops work on the benz as well.
all you have to do is call the shops in your area and find out who would do the installation on the benz. do a search in this forum on remote starter and you'll find out that there are many who have this installed from different places.
good luck.
