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.

First of all, the maps must be created and match the serial number of the GPS you will run it on. Next the maps must be transferred to the SD card in the directory /MAP_DATA The GPS always looks at this directory for any map.

Hi,
First you need to have the relivent map on your SD card. Typicly this will be the Tomtom Map " Western Europe ". When you purchase maps from TomTom you also get an activation code and instructions telling you how to install the map onto your device and how to authorise it using the code that comes with it.
Before doing anything ... BACK-UP your existing data ( the whole SD card ) onto your computer . This will ensure that if any update is unsuccesful you can at least return things to the way they were before you tried to update.
There are several ways to obtain maps

• buy a new TOMTOM SD card for your tomtom that containes the required maps. Make sure it comes with the authorisation card.
• buy a CD from TomTom or a TomTom authorised dealer . This CD will contain the required map so you can download the required map to your own SD card. Make sure it comes with the authorisation code AND instructions.
• buy the required map from TomTom online . You can download it to your PC , then copy it onto your SD card later. It will come with some instructions and authorisation code ...... You can also use "TomTom Home" software and this does most of the job of downloading maps ( that you buy from tomtom ) and puts them onto your sd card for you in a semi-automatic way . If you go down this route then its best to be sure you have the latest version of TomTom home software by going to the TomTom website first.
  

With ANY of the above methods------- BACK UP your existing SD card first . In fact ... make a BACK UP NOW , then if anything goes wrong at any time , you can at least revert back to your backup.

Good Luck

You have to go to Navtec's website. They make the maps, Lowrance doesn't. Yes, you'll have to pay. I paid $90 for the 2008 Navtec US maps. Make sure you buy maps that are on a version 1 SD card, or download them to your computer online. Iway250 doesn't support SD ver. 2 or any SD cards 4GB or bigger.

1. Go to http://www.enzersa.co.za/GPSDownload.html
2. Download the SA Maps Version 6 upgrade.
3. Follow the instructions:
How to use
1: Download South African Maps.zip to your computer
2: Open the zip folder and copy the content by right clicking and copy
3: Insert the SD Card from the GPS unit into the computer.
4: Now open the card through my computer
5: Replace the DestinatorApps folder with the new one

4. Replace the SD card in the Enzer and there you have it!

Best of luck!

Yust go to www.mapwel.biz/down.htm get software MapUpload and now you can upload any map to micro sd card without loosing your existing map.

I have a 310 and purchased an SD card for France from Navman, it says it works in the 310/320/330 so my guess is that a 320 map will work in a 330.

First, some questions:

A. Is the unit turned on and plugged in via the USB?
B. Is the USB connection active?
C. Have you downloaded the USB drivers to the machine you are using?

You can only load one region on the C330. It will not hold the entire update. That is why you are having problems loading it via Mapsource. There is a way to load the second region onto and SD card for use, though.
