[Solved] Adding Map Source on my laptop

Yes it is if you have a map update DVD or download file. If so you should be able to install Mapsource by attaching your Nuvi to the laptop and running the update program. The first thing it does is update Mapsource on the PC, if it finds a copy there, or if it doesn't, it installs a copy.

The next thing it does is create the img file to be transferred to the Nuvi. Once that is finished the actual transfer of the file is started. If you " safely remove hardware" before the transfer to the Nuvi starts then you end up with Mapsource and a usable map file, it can use, on your laptop

I guess the hard part is to "safely remove hardware" before the transfer to the Nuvi starts".

So, this can be done using a map update i.e 2010.40?

I have never had a problem just removing the USB cable from my 660 after the map update begins installing MapSource.

Yes, that's exactly what I did with the 2010.40 map update.

I just disconnect the USB cable from the laptop after it says that it is building the map file for the GPS. When it says later it cannot find the GPS unit just hit cancel and your done.

That's it exactly.

I'll do that today then, Thanks for all the answers!

I do the same procedure and never had a problem with the updates..

I have always updated my GPS twice as I wasn't sure just how to do my laptop only.

It worked like a charm, thanks again for the help!

I did extract the map update to a folder first though, and then ran the setup.exe from the windows folder. It was easier to see when it hit the GPS map update screen. Quicker too!

I've gotten in the habit of extracting the compressed file manually also. That way I know the downloaded file is good and I only have to go through the extraction process once for both PCs.
