Navcore for HTC HD

Good evening all !!

I was wndering if anybody can help me, I want to update my HTC HD running on a 7.9XX Navcore to a 8.4XX Navcore so I can get IQ routes and Automatic lane guidance. Is there such a .cab for a HTC ??

Do I need to uodate the Navcore at all ?? Or can I just update to a new map with such features.... sorry for the simpleton questions, I am new to this.

Many thanks and good weekend !

TOMTOM 7.917 is the latest you can run sorry, Normal navcores will not run on a mobile device
