Europe Map Upgrades - Any Tips?

[irelandbuyer]

All,

I've had a quote in from the dealer of €357 to upgrade the Sat Nav...eeek...

The map itself is pretty outdated tbh and i'd love to upgrade it...but I'm not 100% sure how to do it and if I'd need any discs to upgrade the MMI first? I've seen the packs on ebay but again i'm a bit nervous in case I screw something up...

I took a snap of the map version this morning if anybody has any thoughts, it would be great...cheers....
