Hello, A friend of mine just had his BMW R100 stolen from out front of his house. Most likely he'll never see it again. It got me wondering about discrete, well hidden GPS units on motorcycles so if it was stolen, you could track it down. My understanding is you can buy one for $100-200 depending on the unit but the only drag is battery life. You don't wanna take something out that needs to be hidden once every five days to charge it. However, the bike itself is a charging system, as long as you ride it once every week or so, you'll keep the GPS unit charged. But how do you convert the electricity of the bike to charge your GPS unit? Would you connect it to the battery via some convertor, or run it straight from the AC of the bike's stator? If you connect it to the motorcycle battery will the GPS unit drain your battery and leave you with no spark in the morning? Wondering if anyone has ever thought about this before.
