Pieter, fully aware of that. My point is that if you use a Nuvi or any of the other "softer" GPS's the All in one car radio, dvd player and GPS will do the job just as good if not better for the same price.
You can import one of those jobbies from Hong Kong for R4000 or buy it from
http://www.stopshop.co.za for between R3500 and R4500. Either 1din or 2din.
The Garmin 276C however is a beast of a totally different colour. It is dust and splashproof. It has the ability to overlay Garmap Africa series and T4A and cost about double the price of a Nuvi 760. And worst of all is that the biggest memory card Garmin produces is 512MB at the friendly price of 1800 locally.
I will be upgrading from my current Garmin iQue 3600 to one of these do-it-all's in the near future, 1. because it is cheaper than a new GPS, 2. because it has a 7inch screen which no Garmin or TomTom product can match.
It is a risk because Garmap Mobile XT is not a perfect fit and need a few hacks (all which is available online if you know where to look). However what I have seen make it worth my while. Plus at R3500 for the one I am looking at, it still is worth my while to have rear camera mounted, extra dvd screens for the kids and a nice system even if the GPS proves not to be all its made out to be.
