so.......before you rip me for buying cheep china computer...after breaking my cateye, my budget this was all I could afford.
If you have one, I am not able to get it to switch form km/h to mph. I can reset everything except. if you have one, can you tell me how. There is no youtube, except in german and other non-English languages and of course they leave it in km/h.
If you have one, and you like making videos, you could make a instructional on you tube, as the instructions that come with it are not correct.

Is this the same instruction sheet you got?

My guess would be that you may have to press and hold the "up" button to get it to change.

yep that's the same. No that didn't do it, but thanks for trying to help

it works now. Did the all clear sequence, removed battery, did the all clear again. Left the battery out all night, did the all clear, installed battery, did the all clear, then it all programed correctly.
so it was either that.....or I was holding (sticking) my tongue a different way......or good gremlins
