I am selling two bluetooth OBD2 dongles that I had for my old Android phone. One of these dongles and the Torque app in the Play store is all you need to read codes and other diagnostic data on your phone. I switched to an iPhone and they are not compatible with their bluetooth stack (bluetooth software). I have used one and the other is brand new. $25 each. One is exactly as pictured below and the other is very similar.
*Disclaimer: These devices are sold "as is" without a warranty of any kind. I have tested one and the other I just pulled out of the package to look at. The buyer is ultimately responsible for verifying these work with their device (I have had people in the past claim that electronics I have sold do not work two weeks upon selling).
