Overdrive is just like having another gear, which makes you get better gas mileage. The thing on the headunit,... I have no clue what its for but I bet its not for the transmission.

So as I read the thread name and topic starter I laughed too.

over drive is just another gear for highway cruising the shift button on your head unit has nothing to do with your transmission.

Overdrive is exactly what it says. It is OVER drive, or in other words BETTER THAN drive. It will give you an extra 40-60 HP boost depending on your engine. It also helps with gas mileage despite this instant boost. If you don't use overdrive, you are a fool. If you add nitrous to your car, I would not use overdrive as it will cause WAY too much horsepower boost, and you will be unable to control the car. Seriously, you will probably be able unable to sustain any speed within the speed limit, which will result in endless speeding tickets.

Shift is a feature on some head unit that uses the internal workings of the unit to communicate with the engine to allow your car to become shiftable, that is - your car will be a manual if you turn shift on. You then use the buttons 1-6 that are usually for radio channel to select your gear.

With the nitrous boost, overdrive, and this shift upgrade, I can see you winning many pink slips.

Good luck on all your future modding endeavors!

ok thats enough. Just because this guy doesnt know does not mean you have to talk shit and make him feel dumber. I would suggest you take a moment and go to the manufaturers website if you need info on your stereo man. Im sure some one here could help but you didnt say what your radio is.
