Updating garmin streetpilot
On a trip from Wisconsin to Washington and from there to Tulsa and back to Wisconsin I had to take my laptop so I could reload the maps when we got to Washington for the trip home.I have a friend outside of Toronto who still has one.I had no idea what I was missing until my wife bought me a nüvi a couple of years ago.The Street Pilot III was great in its day, but so was a lot other things we no longer use. The proprietary 128 Meg stick mine had didn't hold much for maps.He's not aware of any data cord that came with it and I don't see a USB plug-in port. Is there any way to update the maps on these, and if so, what are good methods & how expensive is it to do? All the detail maps are saved on that little proprietary garmin card which can be loaded over the serial port while installed in the GPS or alternately you can use the Garmin USB data card programmer (the domed looking device also in the picture).You need Garmins mapsource program and the maps that you can transfer to the data card using mapsource.To be honest with you, that unit is an old dog and I wouldn't put any money into it.You can buy a new Nuvi for what the maps will probably cost if you can find them. Those 2009 maps will "theoretically" work in that unit.
None of the current auto GPS's support NMEA directly.
The unlock code will tie it to the device SN, very similar to the way the nüMaps are tied to a particular nüvi.
