My son has just bought a 2010 Renault Scenic with a built in Carminat Tomtom with a SD card. I have removed the card to access it on my PC and the card only contains the map data. It has UK & ROI map version 840.2568. You can view the internal details on tomtom home by pressing Help. It is running application 8841.453398. It has offered me an update to 8842.
I see from the latest maps that it should be compatible with UK &ROI 925.5442 (currently no meta file available).
Does anyone have any knowledge of whether you can update the map in the usual way once a meta is available? Instead of having a .dct file in the map data it has a .mct file. Is this basically the same?
There appears to be no way you can modify the internal files.
