Upgraded my MK3 Nav system to MK4, V27 software.
No major problems, impressed by the speed, split screen and 3D mode running on my existing 4:3 screen.
The NAV screen is not as bright as it was with the MK3 system, guess it's down to the colour selection. Need to look at changing the colour selections in the operating system..... or buy 16:9 screen.

The overnight battery drain current has dropped from 88mA with the MK3 to 66mA with the MK4.

One drawback, the Tag info from my Icelink Plus/ Ipod is no longer easy to read in full or split screen modes
It looks like the MK4 system writes some fixed data to the same area as tag info, this blanks parts of the tag display.
.... still trying to see what the data is written by the MK4, will look at temporary reinstalling my old CD player to show what is displayed on the screen.

Keith...
what info do you have on date/time data on the IBus ?
I can monitor IBus data on my car but do not know what to expect from the BMW end.

If enough data can be gathered, will look at a PIC/IBus clock system.
