My sophisticated GPS concoction. I’m using my phone with this fantastic navigation app from Nokia called HERE. It would be a good idea to get a dedicated GPS device but this budget solution actually works surprisingly well. Plastic bag: 50p, mount 5P, the thrill of not knowing when it will break on the road: priceless. The windshield actually keeps that relevant handle bar area almost completely dry on the road during the rain anyway. The biggest problem is making the USB connection to the 12V socket waterproof and vibration proof. Currently the USB adapter slips out of the cigarette lighter socket from time to time.
