Hi, pretty new to all this but i have an rac 1100 unit running windows ce 5.0 , thnks to the brilliant tutorials on here i have managed to install tomtom on it running navcore 7.910 and an 890 uk and ireland map and it works flawlessly. My question is would this rac 100 sat nav be able to run a tomtom 8 or 9 navcore or are windows ce 5.0 devices limited to the 7 navcores?
