GPS Without Data?
 

I bought a Pharos GPS Phone 600 several months ago and use it with the Garmin Mobile XT application. It works very well. I want to get a Blackberry and use the GPS on it without a data plan. I gather from reading the numerous posts here that this might be possible, but I would have to download maps to the device. Do I understand correctly that everyone that is doing this having to find maps elsewhere, that there is no company, like Garmin, Tom Tom, etc, that just sells maps on a micro SD card that can simply be loaded onto a Blackberry device?

You can use GPS without data, but you need a BB data plan for most of the map applications. There is a Garmin BB version. Please look at the yellow sticky at the top of the section. It has reviews of most of the map applications and I think Garmin is included.

Also, you can use the SEARCH function.

That's correct. There are a couple of options (neither recommended) in the "All Known GPS Apps" thread as Dubdub said.

MobileTracker and TopoExplorer (both from Skylab) work fine on my Curve without any data coverage. (y)
