Yes. You can download maps ahead of time. I just took a trip to baltimore MD. What you do is get your route first. Then in the "maps" menu select the manage maps and tell it to download the maps along the route. I usually download Zoom level 6 and 3 for the route.

At your destination you'll want more detail so I suggest a zoom of levels 6, 3,2,1,0. That's not too much data and won't take forever to download and is less likely to bomb your SD card (You DO have an SD card right? ).

Another nice thing with MM is that if you walk with your GPS unit you can use it as a "Car locator". If you're in a strange city (as I was earlier this summer). add a POI from your current GPS location when you park and then not to worry about where you left your car, just follow your tracks back or follow the dot.

Oh but make sure you turn off auto download before you start your trip. If you for some reason get out of the range of the tiles you download you'll trip the "downloading maps" function which will cause the IT to attempt to connect to the internet and all kinds of bad things can happen the worst being draining the battery.

You can use the Navicore software and map without an Internet connection or GPS receiver, but you cannot print out step-by-step directions like Mapquest.

I considered getting this kit but after a trip this weekend using mapper I think that is sufficient for most things I do. On my mobile phone I have smart2go so if I really need a navigation aid I can just pay for it OTA.

What other Bluetooth GPS units are compatible with the N800? I have been trying to search the net to no avail. Anyone have any info?

Have you tried searching on this forum?? Try "bluetooth GPS receiver" in the "Search" feature at the top of the page (not "search this thread") and you'll get a lot of info including units compatible with Nokia IT's. For example:

The true magic in these forums is the Search feature - all of your questions have been asked and are ready for you to retrieve.

Maemo Mapper is really awesome but it shuts itself down on my n800 randomly. Also, I've been searching the forum for hours now and can't find what I need... I've been able to download maps from MM, and I've been experimenting with Winmapper. However, winmapper isn't doing the trick. I'm downloading an area map on google streets with it but when I view the map on MM, there's sections missing and enlarged. It looks really weird. Any idea? Is it Winmapper, MM, something else?

No one knows?

For WinMapper, it's a known bug : it generally download 95% af the requested maps.
Just clic again (and again if you want) after the 'completed' download to download again the maps : it will download only the missed ones.
For Mapper, it crashs often when it lost the gps signal (gps disconnected or signal too far).

Does the CR-86 feature AMPS compatible mounting holes?
