I’ve had my Samsung i-730 for almost a year now and since I got Google Maps for it and with unlimited data package with Verizon Wireless, I decided to give this GPS thing a try. My PDA phone has Windows Mobile 5 so it was a bit different to setup.
There was a addendum to setup your GPS wit WM5 and I was more or less on my way! Basically, you have to set it up like any other Bluetooth device detection method. Turn on GPS first, have your WM5-device search for a BT device, and select it and assign it a COM port.
You then assign a new Outgoing COM port to it. Then in “Settings” –> “System” –> “GPS”, make sure you set it up for same COM port in “Hardware” port setting and set it for 4800 baud setting.
I have Google Maps 22.214.171.124 installed and once I clicked “Track Location”, I began to see blue dot on the map and as I drove home from work last night, I saw my location moving!! It is the best $35 I’ve spent!
There’s a car charger so you can charge it and placement doesn’t seem to be too sensitive as I left it in my center console. This would also work on a laptop with Bluetooth and a mapping software… Overall, I give it
9/10 for no-nonsense awesome GPS!
