I have a Renault Scenic III built in 2010. It's equiped with the Tomtom carinmat system, not the newer LIVE version. I'm using a new 4gb SD card with the new europe map 870.3413. My current navcore is 8841. I saw there is also a newer 8842 navcore. Everytime I start Tomtom home it wants to install the newer version. I did this once and tried to hack it seemed to work but I couldn't use any maps I downloaded so I went back to NC 8841 again.
I'm wondering what or if at all I'm missing anyhing now; I mean whats the difference between these two versions? is it possible to use the 8842? if so; which map do i need?
