If you buy the actual iCarScan – it comes with a license to download 5 manufacturer’s diagnostics software with 3 special functions . That’s not models – it’s the entire line of each manufacturer (Toyota includes Lexus.. etc.) That is included in the price. You also can download 3 basic “functions” software – things like resetting oil reminders for any car, etc.
The value of this vs about everything else is – it’s not VIN# limited (Durametic only allows 3 VIN#’s to be used on their DIY version, and the pro version is very expensive), and it covers more than just Porsche.
Plus since the software runs on a cell phone, you can toss this in your door pocket and have diagnostics on the fly whenever you want to. No need to lug a computer around.
