Ebay (or other) MFD 2 sat navs

[Vee]

Plug & play in a Mk4 and I think its the same for a Mk5.
Check on www.uk-mkivs.net - there are a few good how threads.

Also, there is a chap on eBay selling from Poland that many have used with no problems.
Can remember his name but the theads on uk-mkivs will refer to him.

Plenty more info on http://vwnavi.com/forums/
