Yeah, I bought the above for the speedometer and odometer. Trouble is, I've tried going through the instructions, settings, and menu's with no luck at all. The instructions are vague at best, and I cannot even get it to bring up where to input my tire circumference. Very frustrating!
I'm now tempted to eat the $40. loss, and just get a GPS instead. I should have done that to begin with, but cheaped out.
