Hi Stacka....this Powerlet cable may help you. It plugs into your Triumph power point and is a Y cable that has 2 SAE ends....one to power your GPS and the other for your phone. You can still charge your battery. You just need to find a spare SAE end to solder to your GPS cable. I use this set up for my GPS and Ipod power. Have a safe trip.
