I'm so old-school that I still use maps and find East when the sun rises. I don't have a GPS, don't have a Blue Tooth, (don't really know what it is,) just a knock-off MP3 with earphones. I've always wanted to have a CB radio on the bike, though I've never used one at all, just the radio comms in the military. Does anybody use them much anymore? What components would you need? How do you PTT on a bike? I googled but I couldn't find anything. Does anybody on bikes have CB radio anymore?
