There is a power socket specifically designed for a GPS unit which can be found behind the left hand signal pod. There are instructions on this forum which guide you through the fitting. For the heated clothing you will need to either wire direct to the battery but fitting an appropriate sized fuse or connecting into one of the 12v power sockets on the bike itself, there is one by your left knee when riding, one on the left side just below the pillion seat and one in the stowage box in the fairing. If you have an optimate lead fitted you could use that also but you would need to have an additional fuse wired in.
