Ordered a i-Blue 737 from buyGPSnow
i-Blue Edition 2 (i-Blue 737) - High Sensitivity Bluetooth GPS Receiver (51 channel, WAAS, Auto On/Off) (Your Choice of Free Mount) - buy GPS Now on Wednesday. It arrived today via USPS priority mail today and the shipping was free !
Charged and paired it with my Curve without any problems. I downloaded nav4all and for $50 I have a fully functional GPS application !
Awesome little GPS receiver. I can place it in a change compartment of my dash in my F150 (with no direct sky view) and the reception and precision is awesome. It uses the same USB charger type as the curve, so one less thing to carry around.
Also works well with Google Maps and MS Live.
Picture shows size relative to the Curve as well as the small wall charger.
