Just to update this thread with details of how you can change the "Welcome to VW" splash screen to the "SEAT Media System" splash screen.
I posted it elsewhere, but copied it here for anyone who has bought a VW RNS510 rather than a SEAT one.
I'm assuming that you have a VW unit and a PC with internet at home, and a dvd burner.
I use Firefox, this might be different on IE or other browsers.
Click on

go to the Volkswagen tab in the black bar across the top and click on it. This brings up a gallery of images. The OEM screen for the SEAT Media System is the second one down in the left hand column. (there are other Seat ones, but they are few and far between.)
Left click on the image and this brings it up on a pop-up window. Select Volkswagen RNS510 from the list under the large pic and then right-click on the large pic. From the list select "save image as" and save it to your PC, somewhere easy to find. It should save as a PNG image.
Now, go back to your internet and the netdata page you were on. Click on Home in the black bar across the top.
Step 1, select Volkswagen.
Step 2, click browse and select the PNG image file you just saved to your PC, and upload it.
Step 3, click create ISO file. This should convert it to an ISO file.
The next pop-up window should give you the option of what to do with this file. Select save file and
store to your PC or open with and use your burning software. I use DVD Decrypter, they also suggest Nero.
I then burned the file to a DVD R.
Check out this video on
http://www.netdata.be/iso/?action=howto or from the
HowTo tab on the black bar. It's not english but shows the sequence of events. Most is automatically done by the unit itself.
Go to car. Turn on unit by power button, not with key in ignition. Press and hold the eject, the i or star button next to it and with another hand the setup button. The unit should go into setup mode. Insert the disc.
when you get the message Do you want to proceed press YES.
When you get the UPDATE SUCCESSFUL press eject and remove the disc, the unit should restart in normal mode. And you should have the lovely Seat Splash screen.
Cheers,
Roy
