I just got a waterproof motorcycle gps unit that I want to be able to connect up to the bike's battery so I don't have to worry about it going flat when I am out riding. I want to do more overnight trips so it will be getting used for full days travelling in unfamiliar areas. I currently have heated grips hard wired into my ignition switch. I also have a trickle charger and I leave the ring terminals permanently connected to the battery with a connector (with waterproof cover) just hanging out from under my seat. The gps unit came with an cable that connects to the gps, has an inline fuse (or DC adaptor?), and an end line that is meant to be wired into the bike electrics. I was hoping that someone knows if it is possible to get a connector that could I could put on the end line of the gps cable so I could use the cable already connected to the battery. The attached picture shows the connector I am talking about at the top and the bottom shows the gps cable with the end line. My other option would be to add an addition cable to the battery via terminal rings with an in line fuse and maybe just a mini usb plug on the other end. The gps has a mini usb socket that can be used for charging or connecting to a PC to download a personalised route map. My bike is only a 250, so not sure whether it is possible to connect too much.
