If you want remote start feature as well, you would have to purchase a remote start/security combo... in that case, basic install is included. 

Additional costs for you would be a bypass for remote start + bypass install roughly around $130

keyless entry is $50

If you want the temperature check, make sure you get a unit that has that built in, Viper does this very well and you can change between F and C on the display. note that you will definitely want the 2way remote for this feature!!!

That should about do it, but make sure you talk to your local installer for an exact quote
