I copied my original SD card to a new one. Copied navcore 8842.542199.Carminat_tomtom over it.
Then i used Carminat tools to extract my bif file to the root.
Used the last FastActivate to crack the Maps(succes).

Now is my Carminat terible slow. Loading maps and just driving updates 1 per 2 seconds.
Does someone have the answer?
