If you have Navigation software DVD you use it to get pre-installed map back or if you don't have then Contact Sanyo for navigation software DVD, This software is basically a back-up disk.

I would recommend you to reset your device before installing (Back-up disk) the navigation software:-
There are three ways to reset the device.
1) Soft Reset:-

  • Take a sharp object like a pen and depress the reset button located on the bottom of the device.
2) Hard Reset:-
  • Disconnect all cables, including the AC adaptor from your device.
  • Use a sharp object to slide the battery ON/OFF switch on the bottom of the device to OFF (left) position.
3) System Reset:-
  • In the Main menu, tap System, then System Info.
  • This will allow you to do a factory reset. (restore to default settings)
  • Reset the GPS and re-calibrate the touch screen interface.
I hope this information will help you,

Good luck and have a nice day

If you delete all the information and dont make some back-up, its so hard that you can recovery this data. I suggest visit your delaer site and updated this maps from there.

Some programs recovery delete files, but alot times, this files are recovery with wrongs.

    The SANYO Easy Street NVM-4070 units give you the option of utilizing TMC, the Traffic Message Channel. This application broadcasts real-time traffic information, alerting the driver of any upcoming problems on the planned route. The Auto Reroute feature will calculate an alternative route so you can avoid the incident. A free 90-day trial of TMC service is included with your Easy Street NVM-4070, check it in this link:

    Keep in mind that its possible that you need any "reset", to do it I suggtes check the User Guide (page 43)

This unit comes preloaded with maps for the region in which it was sold. It does NOT contain maps for the rest of the world (unless you purchase specific maps from Garmin). If you were given a C340 preloaded with maps of the US and you want to use it in the UK, maps for the UK must be purchased (if they have not been already) from Garmin. They can be found at or your local GPS retailer.

I don't have the Eu. map preloaded on my T.T.910 T.T. is playing games, trying to sell me the map. No way Jose ! Who's got a solution ?

Usually you have to buy the maps unless they are preloaded. The 910 should have the US, CDN and Europe preloaded, so stand your ground and write a brimstone-smelling letter to the TT HQ. You should have the maps with the unit. If not installed, at least on a disk or a download voucher.

Going to Mexico and my garmin will not display it.

There are a variety of Garmin® GPS devices that come preloaded with mapping not just for the United States but also for Europe and Mexico. Any nuvi® that has 70 in the model number will have preloaded mapping for North America and Europe.

Example: nuvi 270, nuvi 370, nuvi 670, nuvi 770

Also, some specialty models will have preloaded mapping for North America and Mexico. These units include the nuvi 200 Mexico (p/n 010-00621-2A) and the Nuvi 260W Mexico (p/n 010-00656-37).

To obtain Mexico maps, go to this link:

My garmin says it can't unlock the maps

If you are getting a Can't Unlock Maps message, you have a problem with the map unlock code on your unit. If your Garmin is not a preloaded device, you may need to verify that you are using the correct unlock code and re-install your mapping software.

If your GPS is a preloaded device, such as a nüvi, or if you cannot get this issue fixed with this information, please call Garmin at 1-800-800-1020 for further troubleshooting.

Have problems with the loading of the map XPC415S. Australia East coast. Will this map work with this unit?

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.
