Thank you very much PeterHimself and biggerdave for your reply.
For my question 5., on the TomTom website, if I order thé map "Map Of The World - Latest Map + 4 Updates Per Year" in the section "Maps for your sat nav" instead of "Maps for-in dash" (to using the voucher emaxmsp2212tt2), is the map going to work in my TomTom Carminat Live car ?
