What do I need to get update maps for my computer,

Has yours been updated recently? I updated mine, (about a year ago), on the website and it wiped all the map data.
I think some of the more recent software update versions have caused problems for certain sat nav models.
Try logging onto the Garmin website, connect you sat nav to you computer and check it has the current software updates. Older models sometimes need to be reset to an previous version of the software to work correctly. To do this you might have to contact Garmin directly by Email to get them to send you the correct software version.
Hope this helps.

Would need to connect TomTom to your computer to do so.

Remove you sat nav from the car (I am presuming it is not factory fitted) attach to your computer via a USB cable there will probably be a USB mini or micro socket on the sat nav, you should have been supplied with the correct USB cable when you bought the unit.
Once you have connected your unit to the computer go to the sat nav manufacturer website and select products. Go to your product and look for downloads or updates.
Also check that the sat nav screen isn't asking you questions to communicate to your computer. Sometimes you have to agree that the unit an talk to the computer or nothing will happen.
When you have found the relevant update save it to your sat nav unit being carefully not to unplug the USB lead untill you are completely finished.
When you restart your sat nav it should be up to date.

You connect your satnav to the computer with a mini USB lead. The narrow part, which is the same as the plug on the car charger, goes into the back of the satnav in the same socket that the car charger goes into. The USB connector goes into the USB port of the computer.

If you didn't get a mini USB lead with your satnav you might have one for another appliance that connects to your computer which would do the job. The same type of lead comes with most external hard drives and some camcorders and digital cameras. They are also sold in computer shops.

Garmin Sat Navs do this when the map is one year old. It can be updated by going to the Garmin website www.garmin.com. Connect your Satnav to your pc and register it if you have not already. The site will lead you to your update which can be downloaded if you have broadband or posted on DVD if you prefer. It is expensive so you need to consider if it's worth updating or not.

The tomtom GO 300 does not need an installation disk. It has firmware ( thats a sort of pre-installed software ) that is put on it at the tomtom factory. If the firmware has become corrupted it can be reinstalled or "updated" by logging on here > http://www.tomtom.com/plus/service.php?ID=17 then click the DOWNLOAD TOMTOM HOME Link. Then connect your tomtom to your computer with a USB lead. Run the TomTom-Home software you downloaded and select "UPDATE MY PRODUCT" . After that , if you don't already have one you will need a valid SD card for your tomtom containing the maps for your country and some other activation codes which you get when you purchase maps from tomtom.

Did you try zooming either "in" or "out" ??? Did you verify that the new maps are installed? Did you try doing a reset?
