Thought some of you guys might enjoy this. I recently purchased a Bluetooth OBD II transmitter to link my Sprint HTC EVO 4G to my truck. It is one of my favorite apps. When I have a check engine light I plug it in and it will tell me my code, pull it up on the web and give me the best fixes for it like an ALLDATA and I am able to clear them. I have about $30 into the whole thing. You can get the Bluetooth OBD II dongle off ebay shipped for around $25 and then $4.79 for the non advertised app off the Android market. Works on 1996 and newer vehicles, or any vehicle with OBD II capability.
