    Problem solved, and installation completed O.K. Would it be possible to mention in the product Manual that a USB cable is required for downloading Updates and Software, as there is no mention of how the unit is to be connected to a computer for this procedure.

I did what I should have done first. That is , I looked in "Help" and found that I should use a USB connection. My only problem now, is whether a standard USB cable is O.K. I have one with the right size end connectors and assume that it is right to use it. Thank you for your reply to my request.

How do i upgrade my garmin nuvi 200 gps? (never been upgraded


Download and install the Garmin commuicator plugin to your computer
This will allow the nuvi to transfer data back and forth to Garmin's server.
Connect your nuvi to your computer and run the Garmin WebUpdater to update the software on the nuvi.
Download and Install WebUpdater.
To update the mapping, you will need to purchase a map update subscription.
Once the subscription is activated and registered to the nuvi, follow the download instructions to download the map. This will usually take from 3 to 4 hours or more depending on your internet download speed.
The nuvi 200 is a discontinued model and you may want to consider upgrading to a new GPS as a new nuvi with lifetime mapping can be purchased for about $150.00.

For further assistance you may want to contact Garmin support.

I downloaded a free map upgrade for nuvi 250w. I didn't realise that I'd need an sd card. Now I seem to have lost some european maps. Can I retrieve them?

The problem with trying to put the full map of Europe on the 250 is that it doesn't have enough storage space. You can download the complete map however to your computer. The option to download again is available for approx 30 days. When it's on your computer you can select which maps you want to install to the satnav and install the complete map, if you want, to an SD card. You need a 4 Gb SD card to hold the complete map. To download the map again, to your computer, log into myGarmin. Click on the myMaps tab at the top of the screen. There you'll see the map you downloaded. Under the map name you'll see the word "Details" in blue. Click on "Details" and it will take you to a screen where you have the option to download the map again. When you go to download the map it will by default select your satnav as the destination. Change it to your computer so you get the whole map and you can add or remove maps whenever you want.

You can download the entire map to your computer and install the part you need which can be changed anytime once you have it on your computer. Alternatively you can try installing the full map to an SD card but there's no guarantee that it will work once you've installed it to the SD card.
