I purchased one of these devices from www.mobilefun.co.uk and it was delivered within 24 hours. the device is instantly recognised by btplugin and maemo-mapper and works really well. Simple & inexpensive GPS option for the 770. Just waiting for flite to be ported to OS2006 so I can use it for car journeys. Also works fine with Nokia N70 phone (tested it with Wayfinder & Nav4All sofware).
