Tomtom 520 driver not installed,not syncing with laptop

It may be losing its IP address. Check the DHCP address affectation of your router. And leave your printer constantly connected to the router. You should also let your printer get the IP address automatically upon booting.

Sounds like you may be having an issue with software already installed on the laptop to control the wireless connection. Many laptops have preinstalled software for their internal wireless devices. You should consult your manual about configuring and saving passwords for a network for that particular device. Typically you will need to enter the WEP key in the software itself.

A couple solutions:

1) Make sure the TomTom can "see" the sky well... the GPS satellite waves are rather weak and easily blocked by trees, and anything not a window.

2) Hook up your TomTom to the computer (see details at www.tomtom.com or in the manual)

2b) Do a "sync" and download all updates. One of the updates is a small file that tells the TomTom where the satellites are located this week, and helps it sync up much faster. The longer time between uses, the longer it takes TomTom to find the satellites, and that can takes up to 2-5 minutes sometimes.

That can be frustrating with a car full of people waiting to get going and the driver doesn't want to drive without making sure the TomTom works and is giving valid directions.

You have to use TomTom Home software to dload and install maps. DO NOT do this with your cell phone...

Computer has malfunctioned and windows XPdoes not recognize it-

I had the same problem until my wife quickly figured it out.Touch the main part of the screen and then touch change preferences.Hit the forward arrow several times {4 on mine}then you will see "set clock".I'm not sure if i have a 520 ,but it is a tom-tom.

are you sure the sound is not on mute - this can be changed in the preferences section, also make sure the volume is up

my tom tom 510 would start, i have charge the tomtom with green light on, but tomtom is not coming up

tt520 do use a specific file format so it is possible that removing any info on the disk first will help, if this is possible do it through a computers card reader then you can see what is on the card and if you want to format it.

This may be a simple case of removing all the entire active sync directory. If you used to connect via serial+com it wont be detected on usb. Remove active sync from your pc via the add remove program feture, then reboot and re install. Then run the make a connection again from active sync. Hope this helps
