Given you can only show upto ten user icons on the screen at a time you would soon run out. Dependent on unit the built in system has different fuel icons BUT they might not be supported in the standard. I'd have to get up and go out into the cold
. The high has on it show by brand and you toggle on and off. It's lurking down on which icons to show.
The built in icons are different on the standard using Tom Tom data to the high unit based on Here Maps data. I know a local car park is in one and not the other. I did get a non existent car park removed from Here Maps and it went on an update in the car months at a later release. On the standard I'm not sure whether their only source of icons is the Tom Tom cartography or whether the company they use to put the map files together uses a different set of POIs to the Tom Tom ones. I have corrected the Tom Tom petrol ones...
. That's when I'm the codriver wearing the Navigator hat and see that something on the map is wrong... get home and put a correction in
.
I have published the links for budding people to improve the maps via crowd sourcing. Best to take a photo of the feature or / and screen capture the local authorities OS survey map that you can find on most LA websites as your evidence for submission.
To do these submission you register for a TomTom / Here Maps account then:

Here Maps:

Lastly for Google Maps / Waze:

I'm still still waiting for TomTom to accept some road speed changes I gave them with a photo of the signpost. Missing roads they have accepted from me. You get a list of where it is in moderation. Here Maps your change will vanish if it fails moderation after a period and doesnt get passed into the authorised database. This where you would update and ammend the built in Pois and for that matter anything wrong on the maps.
BTW ov2 is listed as a Poinspector file - you should be fine or then this ->. The general purpose GPS utility GPSBabel is the one you hit for convertions when you get stuck on GPS files... running things though it to clean up or convert.
