hi, adress & POI search database is probably located in IDX folders, but unfortunately I didn't manage to update it. Hope you will be able to complete this task. I wish you good luck and look forward for a feedback. thanks

you need to copy those 2 files from main folder of 110MT maps to /00 folder onto your Avic HDD and replace them. You need also to delete folders 01-16 since there's not enough space, but first you have to unlock HDD and attach it to your computer in order to execute required operations. I suppose you know how to do it.

please check this for instance: http://us.lexusownersclub.com/forums/topic/49418-nav-system-usa-to-europe-conversion/

I've found very easy and safe method to update the maps in HD3 device! You can read about it on Toyota's forums. You need only to substitute 2 files: region.kwi and alldata.kwi. I've used the files from 110MT update (2012) and IT REALLY WORKS!!! Everything is fine with my avic after replacing the files. Please note there's not enough space at the partition to copy these files, but you are allowed to delete "MAP" folder from the ones named 0A to 15. UPDATE: it's almost all OK with the navi except for road descriptions not displayed on the blue background located on top and bottom of LC
