Newbie here! I am looking to install compustart cs800 RS, with EVO-all bypass, and wondering if anyone has done this?. Do I have to buy the flash updater unit, or will it work out of the box on my RAV? (units on ebay have version 6 hardware and firmware 4.1 only,.. no higher).Is this a better RS than Viper? I read on the fortin website that this bypass can also function as a standalone RS if its flashed with the updater tool. Can anyone confirm? TIA!
