"Purchase the Bundle Right for You
Garmin Mobile PC is available with or without a GPS sensor depending on your laptop configuration (see versions tab).
Purchase Garmin Mobile PC software on DVD separately if your laptop already has an internal GPS receiver. For laptops without GPS, Garmin Mobile PC comes bundled with the GPS 20x sensor, a sleek, thin, high-sensitivity USB GPS receiver."
