Guide to inserting POIs into TomTom Nav4
use a PC with Ubuntu or Linux or other of the same family.
then you connect the tomtom, but first inside the tomtom insert the micro sd "magic card" the one used in point 3 to be clear ... to enable "Enable ADB and root"
then put the tomtom in recovery mode with the micro sd inserted, to do so, press and hold the power button until the black screen with white writings appears, then wait 1 minute and then press the power button 3 times quickly and in a row like this that the tomtom remains stationary with the tomtom logo, so now you can connect the tomtom to the PC with Ubuntu.
immediately it displays 2 memories, one of 7.8 gb or more and the other of 34 mb, the first is the internal memory of the tomtom, the second the micro sd.
then go inside the tomtom (7.8 gb memory) then follow this path:
DATA / TTCONTENT / COMMON / ISTALLED / LOCATIONS
and inside this Locations folder insert your .ov2 files and also the folder with the icons, that is the folder: ov2_icons
an example of the icon files I put it here, so following the scheme and the various resolutions then you create them of your own:

Link URL:

Only the registered members can see the Link URLs. Please Login OR Register.

N.B. ... do not delete anything inside the tomtom otherwise just do damage and insert only the POIs where I told you, then disconnect the tomtom and restore it:
MENU / SETTINGS / SYSTEM / RESET DEVICE
When the tomtom restarts it should give you a new list then inserted and you can find them under: My positions, but above all you can find them in this path:
MENU / SETTINGS / APPEARANCE / SHOW LIST OF POIs ON MAP
here you will find the icons of the respective POIs that you have entered and you can leave them active (SHOW) or hide them and not show them along the way
... it is important to restore, otherwise it may not display well icons and pdi ... and for MENU I intend the 3 dots ...

SORRY FOR MY BAD ENGLISH !!!
