Sat Nav Disc - Which One????

[madslug]

Which disc would work in my 99 Elite? It has a disc player/reader in the boot and the disc that is in there at the moment is a 2000 Navtech disc. Because it's old there are loads of roads missing (including mine)
There are discs on Ebay but I dont know if the 2006 or 2007 discs work in the old units?

You need a Philips Carin/VDO Dayton compatible disc which will work fine but a little slowly as the modern discs are far larger with alot more info. BMW branded navigation discs will also work and are often the cheapest
