Route 66 does have South African maps. Just go to
http://www.66.com. They had an add in the Vodaworld magazine a month or two ago. I haven't tried it though so I can't comment on its functionality.
The initial .
za maps page I landed up on was a huge let-down as it appears to support only the 'doze Mobile 5 series

- Imate, Qtek, et al ahoy! But some digging through the menu system on the left unearths options for
CD-only which at $180 (currently a hair over R1400) is bad enough, but when you get to the
miniSD kit that gets upped to $419! :cringe: (though, to be fair, you do get a whole bunch o' stuff inside), but still...! There's also an
upgrade pack which must be of some value, but I can't see it RHRN

- and if you're already dropping that much tom on the system, it may be worth the (relatively!) 'mere' $90 expense .."in for a penny, in for a pound" and all that.
It's worth checking out the
Flash demo (upbeat but somewhat cheesy) for an idea of the UI and functionality; also, from what I saw, it looks like this is self-contained - no extra connection to get map/route data, a la Nav4all.
