Latest version of Google Maps for Mobile (V1.5.1) now has GPS support. I know a lot of people have been waiting on this one!

go to Google Maps on your phone to download.

Just tested and confirmed it works on Pearl with external Bluetooth GPS, apparently 880 works also.

To get it to work, select 'Bluetooth GPS' in Menu, sub menu with SPP slave or Serial Port appears.

Select SPP Slave and you are good to go. I needed to switch bluetooth on manually. A little flashing blue dot appears on the screen.

Very cool!

This is somewhat old news, RogueOne.
Google Maps 1.5.1 has been out for a while, and has been discussed in pretty good detail in these forums in many threads.

This might be asking for alot but does anyone know of any marine/maritime maps for use with GPS?

oops - didn't check far enough down forums. my bad
