can anyone give me any indication of what il need and costs involved?

There is already a guide on here I think Steve.

You'll need an MFD unit, GPS antenna and a plug and play lead. You'll also need a CD changer mounted under the seat if you wish to listen to CD's whilst navigating.

Skoda branded MFD's are hard to find.

Have a look on ebay, iv seen a few VW models on there.

how much are they?

eBay will be your friend.

is £400 a rip off? on there

£300 if your lucky mate!

£400 is expensive but like I said they are rare.

not seen many Skoda sat navs on ebay so probably not.

When I was looking at getting one for the fabia I was looking at one of the VW or Ford units, I think the only difference is the LED colour and the starting screen.

one was sold this morning went for £200

barging. i have vw one with green led conversion.

now just have to fit it, darn cd changer lead. too short.
