Glad to be on gpsunderground. I have a Teletype WorldNav GPS I bought way back in 2007. It has win ce 4.2 in it. I installed NDrive on it with Indian maps, courtesy gpsunderground threads. NDrive seems to be very stringent of GPS signal and the GPS locks I get are too few and far in between. I am thinking of upgrading my GPS OS to Win CE 5 or 6 since most GPS software seem targeted for these recently. Before I throw away this GPS I was just wondering if its possible to upgrade. I read somehwere else that the core OS is dependent on the vendor and they will have to provide the same. Is that true? Is there no way I can upgrade? I installed this great set of tools from the thread How to unlock any gps wce 4.2/5/6 and now I am able to see underlying windows in the device which was earlier masked. Any tips anyone?
The OS is usually burned into a rom that is soldered to the gps circuit board. That makes it very impractical to change the operating system, unless the vendor has built a re-flashing interface into the device.

Witch cable are you using for the upgrade ?
