Satnav system stoped working. Kia not interested

In October 2013 I bought top of range Sportage from Kia 4 Ways. One of few vehicles without std Satnav (GPS). Paid R10000 for fitted satnav & sound system (ICE). It was clear from start that it was inferior product but no help from Kia. Last month the whole screen went black. Manager managed to get screen working but the satnav system does not even switch on. No interest from Kia. They stopped using ICE and a few months ago they were liquidated.<br> <br> Kia chose and recommended the system which I assume was their standard system - no option provided and customised for Sportage.<br> <br> It is my view that Kia responsible for the product. I paid them for it on their recommendation under their guarantee. They obviously knew it was sub standard which is why they discontinued using ICE soon after fitting my system. It needs to be replaced. If I try to trade in my car later this year the value will drop significantly! <br> <br> The complete lack of interest by Kia throughout all the minor problems experienced before it shut down suggest they knew about it and hoped I would go away. In my view it is integral part of the vehicle and it should fall under the motor plan and warranty they boast about. <br> <br>
