Could you please advise me about how to update my GLA'sSatNav - I have been told just put the memory card into my computer and it will update. Can't believe it's that simple and I don't want to lose maps! Any advice please? Thank you.

Hi,
It depends on your sat nav model, year etc. Some you may need to pay to upgrade, think its about £99 from Mercedes but you can pick updated SD cards up on eBay.
