What's the purpose of updating to v32? Please give me the pros nd cons.
Also can i update my z4? Not quite sure of what nav I got.

What Ver OS do you have now? Go to settings screen and tell us the numbers in upper right corner of screen.

Yahtn I checked eearlier i tthink it wwas 20. Whatever a stock 04 z4 has......what the new features on v32

You should update the OS to 4-1/00 (4-1/100). You are very out of date. Carefully download and burn the disk in Mode2Form1 format OR buy the disk from the dealer P/N 01 59 0 141 891. They are 7-10 USD. I just bought a new one from an online dealer for $7.12.

I think ??? the BT retrofit kit for your car is P/N 84 64 0 306 464 and the instructions are EBA P/N 0306466. Ask your dealer to check on that for you?????

What new features will iI get? What about v32?

Where can iI download the one you ssaid I must update too?

What new features wwill it have?

The Z4 ONLY uses the Mk4 nav
The older Mk3 nav cannot be used and was thus never fitted.

The nav drive is in the storage pocket between and behind the seats
The indash CD player is just a CD player, nothing else (ok, it controls the nav too)

v32 has no new features /but that depends on how old your current OS is), just mainly bug fixes especially in relation to the Z4 and the X3
