Imma go with no. They say its plug and play with a mazda 3. Something newer by 20 some odd years than any 12A model. So i would imagine it just piggy backs on some form of sender for all the dash info. Could be wrong by that would be my guess, especially when no professional install is required.....................

I beleive the one that is on ebay just works off of the gps signals. All i could see is that it just told speed and was a gps reciever for your bluetooth enabled phone.
Tell me if i missed anything else it did, but if it were just those two things, it would just be to supply it with power and the gps satellites calculate the speed....thats just my 2cents

First link goes to product page.

Piggy backs on ECU

as well it says its compatible for 3-8 cylinder 4 cycle vehicles

The ebay one, read through it think its as Revvin85 said. And i forsee that being a waste of money. But thats just me i think because IMO Bluetooth is one of the most useless wireless systems, its slow!! So to have real time info thats accurate. I would imagine it sucks. Thats just me.

yeah, i think if you want something like that, a plain ol' gps will work.

thats what i have and it tells speed in real time and is very accurate and it also plays mp3s! and its about the same price with more features....
