The unit has been updated using the disc supplied to work on a 2004 US discAudiA4B6US said:What software are you using? What is the version shown under CAR-Version? Has the US software been loaded onto your Euro unit?
Yes my firmware update disc in index said sofidx:370PROXUS said:If you have original maps 2A and converted EU->US unit then you need to have latest firmware 0110 to use those maps. I feel that you still have previous firmware. It will be enough for 2004 maps but not a new ones.
Find a post about updating to the latest firmware 0110 and then check your maps.
Yes my 2004 map is based on 0020(found inside the Nav disc 2004), the new nav disc has 110.PROXUS said:Question is if your 370 is based on firmware 0020, 0040 or 0110. It it was created from previous firmware you will need use firmware 0110 and change SFIDX to 380. Then upgrade your NAV with that disk and you sould be able to use your new maps.
