The GPSMAP 420S will only work with g2 maps in Australia. I tried all and then was advised by Garmin.

Re: Have problems with the loading of the map XPC415S....

Any bluechart that has been preloaded on an SD card should work.  Did you purchase your chip with the data preloaded or did you download it yourself?  If you downloaded it yourself, try erasing the sd card, format it, then insert the blank card in the 420 and power it up. This somehow preps the chip for the data download.  Then download the bluechart onto the chip and try again.  There is some ambiguous wording in the download screen that makes it look like some kind of error, try the download anyway and most of the time it will work. After the download is complete it should list the bluechart software version on the screen along with some other software info.  If the operating system software is not v2.5 or higher, you may need to download a software update first.

I bought this devise in USA last year where it worked very well.I fished it out the other day but it doesn't work here why?

When you mean does not work, does the unit power up or is it plain dead? If it does not turn on, then you will need to troubleshoot or send out for repair.

If it turns on, but does not provide you with maps, you need to load maps for Australia as you currently have US maps loaded on the device.

Google search for Australia maps for your unit, or contact Garmin customer service.

CN North America NT 2015.40 ([1] Lower 49 States NE)
NE = NORTH EAST... California is not in the North East of the United states. This device only has a small internal memory so you need to use a 4 GB memory card and load maps to that card with MapInstall:

Will my irish garmin 250 work in australia

Your GPS will require a map set for Australia to display your location on the screen. You have several medium choices for street level map of Australia.. you can purchase your choice of an instant download, purchase CD ROM or an SD memory card version to install / load on your GPS. The link above will help you choose which works best for you.

I hope this helps!

Unable to unlock new maps

Where did you download the Australian maps from? If from Garmin, contact Garmin for the unlock code. Maps have to be unlocked to a specific unit.

If you downloaded the maps from the internet, you will still need to contact Garmin for an unlock code.
