SOURCE: Lost Memory and Map Data

I just spoke with Garmin and they walked me through correcting the problem - very helpful. It is a matter of resetting the unit. Turn unit off, then press a finger tightly against the bottom right hand corner of screen, holding it while turning unit on. When screen comes up, let go of power button but still pressing bottom right hand corner of screen, answer question regarding deleting defaults. It is tricky and may have to be done a couple times. Then you will answer questions regarding time zones, etc. When finished with this, turn unit off and go outside in order for the unit to re-aquire satellites. When all four bars on upper right hand corner turn green, you're back in business - or at least it worked for me. Hopefully this will help, but you may want to call Garmin as they are really helpful and can explain it better than I can. Good luck!

SOURCE: Loading Australian Maps on Nuvi 200

She can purchase the City Navigator Australia DVD and load the Australian maps onto an SD card. Insert this into the unit and she'll then have both S Africa and Australia maps.

The maps are third party, and updated annually.
there is a fee for the updates. go to run through the registration process and it should indicate if there are updates for your model.

Hope this is of some help.

SOURCE: Maps on SD card not recognized by Garmin C330 GPS

I dont thinki the 330 handles 4Gb SD cards I think 2Gb is the maximum that is why it isd taking so long and runds out of space so cannot properly load the maps.

How to download australian maps onto nuvi250 with south african maps


It is never recommended that you install the maps in the unit, there is a slot in the unit for an SD card you will have to install your Australian maps to an SD and insert them into the GPS.

Hope this helps!

Hi...I have a Navman PIN 570. When I try use it

The system memory is fixed. The unit accepts cards of 1Gb

You can delete a State and Insert WA if you have the Map disks and they contain West Australia. I am surprised that all of Oz is not installed as the total Australian map is 90Mb and that fits on the SD card easily

Most likely , no , unless its a special pack or somthing.

All Maps are available as installable add-ons, usually sold as a insertable memory card containing relevant map software.

So to get Australian maps on your American TomTom would just require installing the Australia Maps pack.

Garmin C320

Yes, even a 2GB card will work in the Garmin Streetpilot. You will transfer your additional maps to the SD card, plug it into your unit, and then go to the Map System page to activate which map you want to see.

Garmin novii 250

You can transfer the UK maps to an SD card which you can then insert into the Garmin. This way, you'll have both UK and Australian maps on your GPS. Got to Setup to choose which map you want to view.
