The speedometer on the bike is useless, so I use my cell phone app to provide speed, direction and Altimeter (which I find very interesting). The GPS is used for maps and my Delorme is for tracking and messages from family where a cell phone will not work. There is only one GPS here.This looks like the dash of a 757 haha. Why so many GPS'?
I have this issue with some of the USB connectors I use. This will clearly identify me as a redneck engineer, but...if you want to keep your phone plugged into power, the cord attaches at the bottom and keeps falling out as your riding.
