Yes the map navigation thread found one solution that fits all. I documented it in the
resource section.
This
resource is applicable to all Seat navigation systems plus other Vag brands which are MIB2 / 2.5. It is built from the knowledge base on the Leon forum from a long running thread which has the advantage of tracking the twists and turns over...

Basically the units work with any overall.nds file of the missing map card release but not after. So we go back to v1 of the Seat mapcard which is on a Skoda release shown in the thread. Before that I was scrambling about looking for releases to
help people but you didn't have to as it turned out. You could just take the original one from v1. It uses a common feature of mib2 map files any old map can be used with mapcare but not after. Moving the nds file makes the unit think its on that map release.
There is a rinkle on one year thou of going backwards from the release year.
It's this release that fixes 99% of the missing nds file issue.
Take a copy of what you have got on a new bought card. Download the above. Extract out the NDS file out. Copy and try. Failing that try all of the download. When working use the latest download serial 2010 and write the v1 nds file onto it. The link to the latest maps I've put in the
resource. Probably have to use a zoned region now they have popped 16gb or buy a 32gb vag card off ebay if you fancy driving across Europe rather than the zones that fit on the 16gb card. Nds workaround trick again on those.
If its the 1%... hmm. That was covered in the thread. Bit more fiddling. Vag had a manufacturing error with one release on the nds file. I read about that on a Spanish thread and its come up twice now on this board. This might be where the whole release of v1 has to be put in. You can go back just one year before the
problem card if it's that. It gives it a kick.
Basically the nds workaround trick causes FeCs to be rewritten in the unit. You get extra FeCs which you pick up via a scan which you can ignore. Don't worry about any scan errors nobody does.
