3-1/63 is as far up as you can go with MKIII. MKIII is the only one which ever needed the key. MKIV will go to 4-1/100 with Ver. 31.

I'm looking at biting the bullet and upgrading my MKIII to a MKIV, most likely bought off Ebay. Reading through this the SIB says:

NAVIGATION COMPUTER REPLACEMENT - MK III AND DVD NAV
http://www.bmwtis.net/tsb/bulletins/...c_temp/new.gif When replacing a defective MK III or DVD NAV computer, a configuration signal is required to allow the new computer to load the correct software for its respective application. This is generated by using the SSS (Software Service Station) loaded with the latest Progman version, and the navigation system operating software CD V17.1 or V32.

1. Connect the Deutronic battery charger to the vehicle.
2. Connect the SSS via a diagnostic head or an O(P)PS (for D-CAN vehicles) to the vehicle.
3. Open a "New session" in Progman; select "Load SW" and follow the on-screen messages.
4. Select "Retrofits".
5. Select "Languages".
6. First select "Display" to select and/or check the correct languages.
7. Then select "Navigation" to select the languages for the NAV system.
8. At the prompt "Is the CD-ROM present?" select "Yes", but do not insert the navigation CD into the Nav Computer yet!
9. First select the main language and then an additional language (the choices are English, French, Italian, Spanish, and German).
10. NOTE: The gender of the announcer's voice (male or female) can no longer be selected.
    • MK I, MK II & MK III: Only male.
    • DVD-Top NAV, NAVI01, NAVI02 and NAVI03: Only female.
11. After activation of the automatic coding, the DIS tester tells you to follow the instructions on the monitor for navigation CD installation.
12. Place the navigation CD into the navigation computer CD drive.

I thought having read a few retrofit guides that it was simply plug and play between the two, but the above seems to suggest that the MKIV needs to be coded to the car. So my question is do I need to get it coded, or is the above in reference to a brand new unit without software loaded?

If you purchase brand new, then the OS needs to be loaded and the unit coded as per the BMW instructions

If you purchase 2nd hand, then an OS will already be loaded and the nav likely to be coded for the prior vehicle.

Coding doesn't make such a huge practical difference, but you may find the nav may not properly be coded for your radio module. Also, it may not have the languages you want. In this case, my NavCoder software will code it for you.

can someone help me get v32 on my MKIV system.
I would pay for the file upgrade or if someone wanted to email the file, Please help johnnybel

OK, I just bought a 2006 X5. LOVE IT! I got to the "setting" screen and in the upper right I have the following; 4-1/71 so my question(s) are;
1. Which Nav system do I have
2. Is there a new Operating System I should be installing

My Nav disk is; 2009.1.65 90 2 147 669

New to this so any advice is appreciated.

You have a MKIV unit running Ver. 27.1. You should update to Ver.32 to be at 4-1/00 (4-1/100). This forum tells you how to do it. You can download Ver.32 or you can buy the disk from the dealer for less than $10. P/N 01 59 0 141 891.

Burning V32
 

Do I burn this on a normal DVD-r 4.7GB disk or is there something special I need to do?
Thanks,
Ken

Gettting 6 flashes
 

I burnt this file on a DVD-R then a regular CD and all I get is the unit flashing about 6 LED blinks and dont seem to be updating. Am I doing something wrong?

Before you start messing with it, you should do some reading to avoid future problems. Just my 2 cents.
