If you’ve been having trouble finding a large-screen GPS navigation device—say, for your truck or RV—that is within your budget, don’t despair. The solution to your problem might be literally right in front of you: It’s your laptop. For less than $100, you can turn your laptop into a navigation device with software and a USB or Bluetooth GPS receiver module. The Garmin Mobile PC offers a user interface and a navigation experience that are similar to what you get with dedicated devices. Of course, with the inherent form factor of a laptop you give up the touch screen interface and convenience of a dashboard mount. That said, for those planning an upcoming road trip who don’t want to spend a lot, the Garmin Mobile PC is a solid solution.
