Ok, for those of you who have trouble installing the Google Maps (for Navigation), i had issues too, but managed to do it through the following:

1. First, make sure your phone is rooted, then download the Google Maps-ownhere.apk (NOT the re-sign one), and transfer to your external SD card.
2. Using Titanium backup on your phone, wipe data and then uninstall both Google Maps and Street View.
3. Then using root explorer on your phone (i used Super Manager, which also has root functions), transfer the Google Maps-ownhere.apk file to your phone's system/app folder (make sure its set to R/W).
4. Then just reset the phone, and voila! Navigation is available!

There is probably an easier/shorter way, but this works for me. Hope it helps

Rachy, i did not have to manually install the apk file; do you see the Maps, Navigation and Places icons in your apps drawer? It should be there after the reset, no need to manually click on the apk to install.

Glad to see you got it working. Is this your first GPS lock? Might take a while. Mine locks on quite fast. Oh, please make sure u are standing outside and not in a 12 storey building

Sorry Nicregi, missed your post. Glad to see u got it working too
