All 2002 MINIs will have a CD-based (i.e. MK III) nav computer in them. MINI didn't start using DVD-based (i.e. MK IV) nav computers until somewhere in the middle/end of the 2003 model line. Thus, if you have a 2002 MINI, then it will indeed have a CD-based nav computer in it (and so you are very limited with the nav operating system updates you'll be able to get for it).
The version info shown in the settings (or Set) menu for all (current) MINIs will read either 3-1/xx or 4-1/xx where the 3 refers to the nav computer type (i.e. CD-based MK III or DVD-based MK IV) and the 1 refers to it having a premium full color screen (which all MINIs have). The xx will be the current version number of the nav operating system software that you have installed.
According to the following page, the highest version you can install in a CD-based MK III nav computer is 3-1/63 which relates to the v22 nav operating system update CD:

Basically, BMW/MINI stopped updating the operating system in the older CD-based MK III nav computers back in August of 2003. Only the newer DVD-based MK IV systems seem to have further updates provided (they are currently up to 4-1/80 in the v28 update CD).
You can download the latest (for your car) v22 update CD from here:

Also, don't forget that you can update the map data CDs as well (which includes updates to the maps themselves, the address database, as well as the Points of Interest like restaurants, gas stations, etc.). The most current version of the map CD for North America is either 2007-1 or 2006-2. You can purchase a CD for your particular region (or the entire 8 CD set for all of North America) directly from NavTeq from here:

A single region CD is $129 or the entire 8 CD set is $199.
I hope this helps some.
BTW, it's a simple Plug-n-play "swap" to exchange the CD-based MK III nav computer in your MINI with a newer DVD-based MK IV version if you care to do so. I know of folks who have located them in wrecked MINIs and made the swap sucessfully. You can also purchase the DVD-based nav computers on sites like eBay, but they can be quite expensive.
