Since you're not getting it, it probably doesn't matter, but I would stay away from this POS. It was installed on my bike when I got it so maybe somebody else has had a better experience. When shifting gears, it's often wrong. The worst is when coming to a stop, it shows the wrong gear quite frequently - anything from 2nd to 5th at times and it rarely shows neutral/1st switches correctly, although you could argue there's the light on the gauges (but this thing's brighter and easier to see). The worst thing is that there's a delay when it's switching. Sometimes I look down to check the thing is right and I realize that I already know what gear I'm in and most of the time I look at the thing I just want to see if it's actually working right, which it is in general, but it's wrong often enough that I don't trust it.
I guess my real problem with it is that I find a gear indicator is totally useless. I know what gear I'm in from my speed, the sound of the bike, RPM indicator if I look at it. I don't ride track so maybe it's useful there, but it's a waste of money on the street for me. Not saying don't get it, do what you like with your bike, but having had this with my bike, I would never get another one. I'll probably have this removed when I get any major service done.
Note that the design hasn't changed since it was made. This one's at least 2 years old now, probably quite a bit more. If you do get one, I suggest 3M Dual Lock velcro to attach it. The regular velcro came loose and glue wasn't effective either after a while.
