Auto GPS Under $200

Cheap GPS for your car!!

Parts you will need:

• Laptop running Windows 98 or newer, 2GB of hard drive space, and a USB or serial port.
• Garmin GPS18
• Vector 70watt Pocket Power inverter

What to do:

1. Plug in the Garmin, and install the drivers and nRoute and City Select map software. Take it outside and run the nRoute software to let it find satellites. Turn off the Wide Area Augmentation System to speed up the process.
2. Mount the Garmin receiver in your car, parallel to the ground. The windshield mount works fine, but running it out a window to the roof will yield better reception.
3. Familiarize yourself with the software interface and hotkeys. Enter a route. Drive.
