BMW 16:9 Widescreen Displays will work on MKII, MKIII and MKIV Navigation Computers

MKIV is the latest and greatest DVD ROM based Navigation computer. Although it does not play DVDs, the MKIV navigation computer is the fastest and best Navigation computer available with 1 DVDROM map for all of North America.  If the older computers work just fine why upgrade?  HERE IS WHY THE MKIV IS SO MUCH BETTER THAN THE OTHER SYSTEMS

MKIII is the "next gen" CD based Navigation computer that was only available from BMW factory cars between mid 2000-2002.  This system uses 8 CDROMs to map the US, but does support split screen.

MKII is the old style Navigation computer which works with the Widescreen display but is slow and does not support BMW's newest Graphic User Interface featuring split screen functionality.

BMW MKIV Navigation Computer installation instructions

****WARNING  Do NOT DISCONNECT your BATTERY or PULL the FUSE on an with the Key on or until 90 seconds after your key has been turned off.  Always let your Navigation computer spin down completely allowing the red led to turn off see TIS Supplement on MKIII Computers Although this warning is for MKIII systems it is a good pratice to follow.

WHAT IS Mark I, II or III (Or MKI, MKII, or MKIII) ???

Basically the Mark X number determines the version of hardware of your Navigation computer. Since the built in Navigation Computer was launched BMW it has been improved over time. Each major hardware revision has reclassified as Mark something (or MK #).

If your BMW was manufactured from Late 97-2001 and you have a 4x3 display with a female voice it is most likely that you have the MKII navigation computer. MKIII and MKIV were never used with the 4x3 display from BMW (to my knowledge). They work fine, with the MKIII, but they came with the Widescreen display.

The MKII is characterized by:

Car production date: 1997 - 2000 (please note this is not the year model, but the date the car was built)
Female voice for navigation
Separate GPS receiver (there is no antenna in the back of the navigation computer)

The MKIII is characterized by:

Car production date: 2000 - 2002 (please note this is not the year model, but the date the car was built)
Female voice for navigation
Integrated GPS receiver (there is a visible GPS antenna lead on the back of the navigation computer)

The MKIV (DVD ROM) is characterized by:

Car production date: 2002 - present (please note this is not the year model, but the date the car was built)
Female voice for navigation
Integrated GPS receiver (there is a visible GPS antenna lead on the back of the navigation computer)
DVD Based navigation system - uses only one disc to cover the entire US and Canada, or entire Europe.
clearly marked "DVD" on the Navigation Computer.

The MKI is characterized by:

Car production date in 1996-1997 (please note this is not the year model, but the date the car was built).
Male voice for navigation.

It is almost a certainty that if your Navigation System has a female voice it is the MKII or higher.
