We've only had our '03 M5 for 4 weeks but I need some help from some of you tech savy people on how to upgrade the software version. We have the Mk IV with software version v 4-1/12. I believe this is the original software which has never been upgraded. If anyone can help and advise me on just how to upgrade the software to v26-31 it would be really appreciated. I'm not too tech savvy so too much information is welcomed with open arms. Thanks in advance for your help!

Key in position 2. Insert cd from our kindly E55AMG2 colleague. Follow directions on screen. When the disc spits back out get in your car and drive away.
