here's what it says on their website:
Product Features:
* Remote window control: Easy one-touch comfort operation of windows with the original remote on all models (US and Euro) by holding down the power-locks button. No extra remote fob or reprogramming of the key or car is necessary!
* On 987 Boxsters the top can be operated in one-touch mode while the car is halted. Also, top operation is not interrupted when coming to a stop.
* The "Lock-In" feature locks the doors once the car starts moving. In contrast to the original Porsche feature which can only be enabled or disabled at the dealership, this feature is user-programmable and even better, optionally the doors also unlock when the engine is switched off and the key removed.
* Home light XL: The Headlights can be activated for 30 seconds at any time by tapping the trunk button on the remote twice. Tapping the button twice again before the time runs out will switch the lights off immediately.
* Trunk button delay: Prevents accidental opening of the trunk in most cases. If activated, the trunk can only be opened by holding down the trunk button on the remote for longer.
* Chirp on lock/unlock: If activated, the alarm horn will give brief "chirp"signals when locking/unlocking the car.
* Auto-Tilt function for the passenger-side mirror on reverse gear. A great addition for cars without seat-memory.
* Passenger window auto-up fix for all cars where the window will only roll up automatically once it is past half way. Usually found on 997 Coupes
* User programmable: All features can be individually enabled or disabled. Some also allow different personal preferences to be set. All settings are retained even if the car battery is disconnected.
* Shop/Diagnose mode: The chip can be set to be completely passive, as if it was not installed at all. It becomes "invisible" and will not interfere with any dealer diagnostic tools.
so, basically it allows you to roll the windows up/down from the key, gives you aubible confirmation when locking/unlocking your car, allows you to program the door locks on your own, tilts the passenger mirror when reverse is engaged, aloows you to turn lights on at will from the key, and puts a delay so you have to hold the trunk button down longer on the remote to open it...
i dunno about you guys, but it seems WAY to easy to accidentally pop the trunk with the key...i've had a few instances where i found it open when i didnt want it to...i also like the idea of hearing chirps when the car locks/unlocks, so i dont need to be looking at the car for flashes of the parking lights when i park it to make sure it locked...
i also have a similar item on the vette, and i use the window roll up/down feature on it...works GREAT on a hot day...i just roll the windows down from the remote before i get to the car...
install doesnt seem too bad, an article is written for it...
