Email address to contact TomTom
But they do have a form system that pre-screens a possible email that is then forwarded to their customer support system. see this form for a Start 20
This form system, checks which department the support ticket should be raised with, from the screening process front end.
This front end is normally 90% accurate in determining who should be contacted within TomTom.
It should be noted that a reply to the sender may take up to 2 working days to be replied to, so if the matter is urgent it is better to try and phone them during the next working period, remembering that Mondays will have all the weekends build up.
