Can you add third party map software to bushnell nav 500

Try reinstalling it. :)

The only other way to get maps is to look for third party map files. Sometimes they are free. I've not tried to find one for my tomtom but have for my magellan. So if someone has done one then you just need to search the web for something like tomtom map download and the area covered.

You can purchase maps for download at https://buy.garmin.com/shop/buymaps.do?null&ra=true. Garmin does sell the maps for Australia at that site.

There are other maps available from third parties which are compatible but you'd have to confirm that from the seller.

I also have a RoadMate 1200 and I wanted to update my map as well.

After extensive research (and periodically checking up on this every couple of months), I have found that the RoadMate series devices do not allow for any official map upgrades.

There have been reports of successful third party software installations on the RoadMate. Installing a third party software program (or "firmware") would completely change the menu on your GPS. It would be like installing Windows Vista on an iMAC. If it is possible to run an alternative firmware on the RoadMate, then it would be quite possible to download a usable map of Portugal. I have not seen any evidence of this yet. When I do I will let you know! :)

Also, an alternative firmware installation should only be done by an expert computer user. And an expert user knows that alternative firmware will void the warranty and that alternative firmware is VERY risky.

Check out the Terracrosser software, this uses Google maps but allows you to use downloaded maps. Terracrosser works on my S620 although I haven't been able to get my BT GPS unit to function properly with any mapping software. I have tried setting it to COM 6 as previously suggested.

you have to download a third party software to upload the maps, I used GPSsendmap, can be obtained free from cGPSmapper.com.
Just download sendMap20 rev. 6.0 for windows. It works.

I have the new N30 software, it has updated maps and updated software. You can input street addresses and via directions. Contact me and I'll give you a link to download it. Joe

Have you tried to reset the unit?

the same thing happened to my bushnell nav500 gps. Use a pencil point and do a soft reset. I did this and everything came back and it hasnt been any problems since.

I called and the tech called me right back 30 min later, call and give it A try.
