Question about new Nav CD

[mark scheurer]

I have a 2001 X5 with a Mark 3 system running 3-1/31 version software. My CD disc is out of date and I am on the prowl for a new one. I've looked at the threads regarding updating the operating system, however I think I would like to keep what I have because I want to keep the radio station/on-board computer screen, do not want to deal with a splash screen, want to keep the option of inputting destinations while the car is moving, and lastly, don't want to kill my system or pull my hair out like many on the board have done while attempting to upgrade.

Are there any issues in running a new Navteq discin my unit? Do the new discs only work with updated systems? If so, I think I'll just live with a seven year-old disc......

TIA
