On Board Navigator

[Oldmicrochip]

I have a 2010 C5 Mk3 Saloon, fantastic but the navigator chip is 2009/10, could do with an up to date one, 2015/2016 but they are very expensive from Citroen, Ebay could be a good idea, any advice please.

The one I have is a 2013 version bought off ebay for around 35 quid which no doubt is a pirated copy.   I must say I'm not a great fan of the onboard satnav.   I much prefer to use my old Tomtom Classic.
