hi Tell so i ordered a new VAG sd card from the link i popped it into my car and did the overall nds trick the card reads the navigation data but cant seem to load them up. any other ideas you know
Take a copy of it as is.
Then you could try the Seat Mib2 year 1 trick from the
resource. Some units had a "funny" original overall.nds file which causes the upgrade not to work so you load up the earliest release which is the Skoda link, use the overall.nds file on that. That kick starts the unit. Then take the overall.nds file from that release and copy across to the most recent release. So essentially you aren't using the overall.nds file that was on the car when you got it, but a historic one.
This is sometimes required with one particular release of the original map card. That's been successfully deployed on the board a few times. The wrinkle was spotted by a Spanish board. Essentially the card when paired sets up the FeCs in the unit. Moving the overall.nds file frigs it to refresh the FeCs with another set (may get two, the source of the flag being set that you don't need to worry about, and if you aren't worried ignore that bit). For one year only this additiinal process was required.

Lost, Stolen and Missing Cards from a Mib2 Standard Unit
Godzzi and myself covered on the thread the process of getting back a card that was lost or stolen out of the unit. Buy a card and put back the overall.nds file from the year or one before.
For good measure you can go back to V1 Seat map release rather than playing lucky dip with the download releases if you don't know which release was paired with the car, link below and use the most recent map update over writing the overall.nds file with the V1 one.
V1 link (Credit Markobc with that one):

Godzzi tested for me that going back beyond the paired overall.nds file worked. So if in doubt jump back releases if you don't know what the release was. Then do the workaround using the overall.nds file. (I did test that with a unit with the overall.nds of 1030 and works fine with 0430)
Variation of the workaround but going back to the Seat base year for mib2 if no more information on what was in the car. Full credit goes to Exciter for the workaround. Basically now identified that these overall.nds files contains effectively a release date stamp as well as a general database index. For other VAG cars you might want to go back to 0235 (2014/15) which is the very first release ahead of it coming to Seat.
The card needs to be a Standard Mib2 card, can be Seat, Skoda or VW. Might wish to consider the recent 32GB card planning ahead.

Current map release is this, not what Seat put up on their site, that's old.
So I had some free time during the weekend and after upgrading to 515 mib firmware, I decided to give it a go and update the maps too. After some studying I read about the "overall" file workaround and so I downloaded the latest maps. Unfortunately I formatted (and not deleted) the V7 card that...

That may be newer than what was on your bought card or the same.
Kick start with the old maps as is (Skoda link). Shift that overall.nds file onto the latest maps. Reboot of the unit with the long press is always good so it reads in everything a new.
Fingers crossed.
