Gto mine through today and have tested it with Microsoft Autoroute 2002 and works great got a lock within seconds.... its just a pity that the Ms maps arnt as accurate as the GPS!!!
When I planned a route from my house to A.N. Other location the Ms Autoroute startpoint and the GPS lock on my house (where I am testing) are about 50 m apart! and the GPS lock is acctually where my house is! LOL
Havnt tried it in the car yet but will give that a bash later!
