I have a 2000 4.4 with 4/3 navigation system.
I have a CD Nav from 2004 and find the Nav very slow to give you information. For instance, when the Nav tells you to go to right and you go to the left, it takes quite some time to re-direct you to another route. Another example is that the car position while moving in the map is correct, but when it reach the uper part of the screen and the Nav system puts the car is the center of the map, it take some time to do this procedure, and it sometime is says "please waite a moment"...enought time for you to loose yourself on the road.

Are this problems related with the software of the Navigation system, or this is related to the CD itself????
Last week I drove a 2006 Opel with a Navigation CD sytem, and it was a world of difference compared to my X5. Much quicker guiding you, everything´s works much quicker with that Nav system.

Do you think if I buy and 2006 CD it will work better, or is this slowly way of guiding you is related to the old 4/3 navition system?
