You don't have to check any further, you have found your version

You have 4-1/60 (in PC terms: v6.0), which was released Sep 2005

Current version is 4-1/100 (in PC terms: v10.0), released Jun 2008

Upgrade is well worth it. New features:
1. Safety screen auto-disappears
2. City & Town names displayed
3. Destination input improved

and bugs fixed.

and enabled function of reading DVD-DL disks......

I having problems after the V32 update from v27.1

I have a 2003 M3 with the MKIV DVD based nav. I followed the instructions and the software update was successful. The CD was ejected and the system restarted. I put in a 2006.2 and a 2002 map disc and it says No CD/DVD, please insert.

From my understanding, the V32 on MKIV for the E46 should work just fine with a single layer DVD right? It is not required to have a DVD-DL in order to use the V32 software?

How should I go about solving this, try to get the 2008/2009 maps in high or professional or installed V32 again?

The safety screen doesn't disappear for all countries, i.e it still remains in Australia.

If you don't like it, turn it off.

Use NavCoder and set Region=Europe and voila! No more safety warning :-)

All other features remain as normal.

I'm thinking of buying such mod from Rolf Resler so i can connect it to my laptop which has USB.

Where do i need to connect in the Mini Cooper?

I've been thinking about this. What do I need, a Resler Interface? Where do I get one from?

So it looks like you have to cut in to the ibus wire? I'd rather not do this, it would be nice if you could get an interface that plugs in to the diagnostic port under the dash.

But you need to tap the I-bus, not the diagnostic connection. You also need 12 volts and a ground.
