Current versions.

[alan sh]

There are two types of maps:

NT maps are for the 550 and 660. Updated once or twice a year
NTU maps are for the newer 3 series and 590/595 and all Nuvi's. Updated 4 times a year

There are separate maps for USA and Europe - not sure about RoW.

The latest that I know of are:
City Navigator Europe NT 2019.10
City Navigator Europe NT 2019.10
City Navigator USA NT 2019.20

Someone can probably help with the NT USA version as I can't remember.

Cheers

No it's not, it's 2019.11

There was an issue with 2019.10 so Garmin eventually released 2019.11

US map is NT, there is no NTU version.

I agree that Garmin Express says 2019.11 is available, and other users have reported downloading 2019.11, however what downloaded to my Zumo 660 is listed as 2019.10 on the unit, so that's what I used.

Really? What gets loaded on the USA 595's then?

The NT map. It's only the EU map that comes in both versions in order to cope with the various different alphabets. The US only has one to worry about

Ah, I see.

I learn more every day.

Thank you
