i recently purchased and imported a 2007 Volvo XC90 V8 from the UK eto Zimbabwe with a Navigation system that pops up from the dashboard and has a DVD reader under the passenger seat< the navigation system apprently does not work in Zimbabwe as the required maps are not loaded< i went to Volvo South Africa and though they have a naigation dvd to install maps for africa they said it wont work as the car is set to European standards, sure i am sure since naigation is sattelite based if i load Africa maps it should be able to work < can anyone assist me hereon how i shud go about this
