The updated maps (Version 8 of City Navigator now from memory) is available from Garmin. The maps are free, provided you registered the unit after a set time - again AFAIC that was 1st Jan 2006. Personally, I wouldn't waste time ringing Garmin, as I've always had a response to the e-mails I've sent them. In fact I don't think I've ever managed to get through on the phone.
The updates for Mapsource ie the computer program is available free just by clicking on "check for software updates" on Mapsource.
You may also want to check the firmware, what Garmin calls "unit software", version on the unit itself and make sure it is current, if not download that update as well.
To update your unit's software:
1. Please go to the WebUpdater webpage by clicking on the following link:

2. You will see a link labeled Download, please click on it.
3. You will be asked if you want to Run or Save the file, please click Run.
4. After the file downloads, you may receive a security warning; if you do, please click Run.

10. After the installation, please ensure that there is a checkmark next to Yes, I want to launch WebUpdater now and then click Finish.
11. The WebUpdater program will launch - again, please ensure that your unit is connected to the computer and turned on.
