What head unit is that? are you using an OBDII to bluetooth adapter?

It is a China unit I got off EBAY. I paid about 400 for it. Got is because it was a pure android (detachable tablet) HU. It worked pretty good for about a year and then started to act crazy. I guess the average upgrade life of a HU is about a year anyway. That display was purely GPS/accelerometer but yes.... you can use OBD plug. I am now using gopoint OBD cable with my Iphone5 and harry's lap timer for all my diag/track info. I might upgrade that to Bluetooth or even wifi module.. but for now my cable is perfect. I wish I could just do a ipad mini mod and have one permanently mounted in my cubby... maybe sometime soon. :-) if you have any other ??'s feel free to PM me.
