I just bought a 2006 Touareg. It did not have a GPS unit installed.

I found a used GPS unit from a 2005 Touareg on Ebay. Bought it. Installed it. Everything works. But....

1) The GPS screen freezes after 30 seconds. When I tap the screen, it takes me to one of its menus. I tap "Cancel" and it returns me to the screen that was frozen. Magically, the screen works again for about 30-45 seconds, then freezes. I keep repeating these steps to make it work, but need to know how to keep it from freezing....

2) I bought new Map disks and am waiting for their arrival. Will this help?

3) Do I need the twin FAKRA connectors? The GPS unit I installed only had (1) antenna connection. Everything works, but the sound quality is not as good as the factory installed radio.

 

Any help will do

I see over 60 people have viewed this issue, but no one is offering any advice.

Any help will do!

Thank you.

 

Yes you need both antennas for the radio...

The freezing isn't normal, so perhaps the unit is not functioning correctly.

 

Isn't there a separate GPS antenna also?

 

yes

 

You should have 2 antenna inputs, one for the regular radio and the other for the GPS. You stated that the truck did not come with a NAV - I highly doubt if it is wired (antenna) for GPS functionality. You need to buy an aftermaket antenna to make it work correctly. Good Luck!

 

there are 2 antenna inputs and a separate nav antenna input (3 total) all need to be hooked up. all have a unique connector so mixing them up is impossible

 

Check software and update this if is old. Should fix problem. Also do a diagnostic to find out if there is any problem with the unit (use VAG and check i measurement block GPS signal etc) If still problem - faulty unit.

 

A couple of years since I was in the dashboard, but you should find a white and beige connector (these two are the diveristy antenna connections) and then the blue connection is for the GPS ant.
