The battery in the Magellan in my car died and I didn't have a charger with me. So I pressed my DInc into service as a GPS unit. I must admit it performed remarkably well. The user interface on it wasn't as smooth as the Magellan, but the Magellan is designed to function as a GPS and only a GPS and the DInc isn't. The only problem I had with it is I couldn't see the screen as the screen was washed out in the sunlight. Is there any way to combat this? How can I use this as a GPS replacement if I can't see the screen?
