I have the Z2 and When I enter a address on the Navigation it keeps saying "Route calulation is not possible" It was working fine before so I have no idea whats wrong. Can somebody help me out?????

i'm goign to be doing some serious testing today. I just had mines installed yesterday, so I'll let you know.

I had the same problem with my dvd80 hooked up to a 5700dvd. I was using a burned copy of the navigation disk. Turned ouot to be the disk. Are you using a burned copy? If so try the original and see if you get the same error!

Hope this helps.

There is no disc...its a z2

The Z2 does't have or use discs. It is all on the internal harddrive.
