I'm at the South Carolina house, and Labor Day Weekend has afforded me the time to start laying out the circuits for the GTM. When I decided to tackle this project, I never considered how much of it involved wiring. After spending the long weekend reading up on ISIS, I am convinced the ISIS Power system does significantly cut the time and complexity for wiring portion of the car.
If you have been around an iPad, iTouch, iPhone or Droid, I'm sure you've figured out that Apps are all the rage these days. Key fobs have eliminated the need to fumble with a door key. If you've had a chance to see late model Corvettes, Ferraris or even our Toyota Camry, they use a button to start the car.
So ISIS takes it another step further (they're probably not the only people doing this) and eliminate the key fob and the key. The ISIS inTOUCH system mounts an encrypted WIFI daughter board on the Master Cell. (The Master Cell is the central brain for the ISIS system.) You then download an app from iTunes or the Droid Marketplace (the Droid App is due out in late 2011) to your Apple or Droid device, and load the encryption key to the app. It can unlock the car, turn the lights on or roll down the windows. Actually, you can set up the programming to do just about anything you want.
If you still want a key fob, they'll sell you last century's technology with their inLINK system. It operates on the same principle of mounting a daughter board on the Master Cell and using radio frequency technology.
The cost difference is $70 and you end up with a much cleaner interface.
