I have a Mazda CX-5 and an iMac running OS 11.2.2, and I need to update my map. I put the card from the Mazda into the iMac, and the TOMTOMDISK appeared. I opened Install TomTom HOME Mac.dmg. I got a message that TomTom HOME needs to be updated. On the window that should move TomTom HOME into the Applications folder, TomTom HOME is crossed out. What can I do?
