Okay, it's more like 'on-dash'.... A while back i looked into getting a Scangauge for my Prius, but to be honest they're kinda ugly and too small. So i looked for other solutions... Firstly i got an Optus MyTab ( aka ZTE V9 everywhere else in the world) reduced $99 AUD which is VERY cheap for a 7" Android tablet w/3G! Secondly i ordered a Bluetooth OBD adapter off Ebay for $20, and lastly i got a 30cm strip of Velcro for $5. My 7" in dash, internet connected, navigation equipped, text message and phone call capable costed me only $124 AUD / $131 USD / 80 GBP, a scanguage would have cost above $150... The black velcro was stuck over the blank (pointless) radio area, covering the disk slot, hazard light switch & clock... The tablet blends into the dash better in real life than in the pictures, the piano black on the tablet ties in with the piano black dash... Google's places app for finding restaurants, bars, ATMs, parking, petrol stations etc etc, it even shows you reviews of the place, it will give you turn by turn directions, you can phone the business & view it on streetview ^Maps and navi etc w/traffic, super useful as my prius doesnt have Nav Bluetooth OBD adapter The best Android app ever!! 'Torque' runs from the bluetooth OBD so i can see my engine revs, engine load, throttle position, instant and average economy, fuel level, GPS speed etc You can also monitor transmission, coolant & cat temps etc, plus a whole heap of other widgets. Over all i'm super happy with it, well worth the cost!
