Cheap Chinese OBD-II Wifi and Nav Screen
 

I'm interested in purchasing one of those $80 OBD-II wifi dongles on Dealextreme.com and using either Rev or Dashcommand on my iphone to output to my navscreen different stats using the composite (RCA) input in the console. I will need to disable the parking break and speed sensor for the nav (explained by others on this forum).

My question ... has anyone already done this and if so was it useful? I have jailbroken my iPhone and hooked the output from TVTuner to the composite inputs and its not that great of a picture.

The cheap ones I see on ebay only say up to 2010, not sure about this one, but I would also like to know. I already download rev or dashcommand from installous, just need the wifi obd2.

OBD2 is a standard and as such does not change between 2010, 11, or 12.

cheap ones are very slow. I saw a review on mp3car.com about this one.
