Just wanted to let everyone know that the Sony GPS dongle(PSP-290) is now working with the Latest version of Map This! software by Deniska. You make your own maps with google or msn and off you go. This app is only for 3.03 OE-B firmware. I ordered my PSP-290 from Play-Asia and it works very well. It usually needs about 1-3 minutes to lock on the satellites and then works flawlessly. These units are not region coded so they work everywhere. For $60 plus shipping its a very nice portable GPS system.
