    The larger file will contain more junction views than the smaller one. Choose according to storage space available.

    More jcv images in the larger file as said by Smokefree. The small one is maybe for Western EU only[?].

    I think the sole OEM CN EU mapping for zumo 3x0 is the unicode version: [Only registered and activated users can see links. ] [it uses split-screen JCV file].

    If you use NT you cant use JCV with picture size 212*234.
    (I think you are using SP, so you need NTU map and NTU addition files)
    Yep, I am using street pilot on my Android so I will have to re-download all Europe NTU over again. (I suppose JCV from NTU is not compatible with the map from NT)
    Thank you for letting me know.

    Caty means that quite literally, 'you need NTU map and NTU additional files'. JCV files are totally map dependent, the JCV from an earlier NT won't work with this 2015.20 NT.

    Thanks for the replyís folk, But I could clearly see there was a significant difference in file size between the two files after downloading them, What was actually throwing me slightly being relatively new to Garmin
    Was the actual naming of the two files, Was kind of hoping there was a typo on the picture size 480*270 in the file named JCV full screen & that it would actually be full screen images, because that would have looked absolutely awesome on a 7Ē screen

    A bit Like this image [full screen]

    moww3


    Rather than what i seem to be seeing [Split screen]

    2v2fhfq

    Note: images taken from the internet

    Anyway thanks all for clearing my question up

    But I think in future the files would be better worded like, JCV Full & JCV trimmed [for them thatís short on storage space]

    The above got me interested. I assume you're using this map and the jcv file in your DNX7230DAB. The Kenwoods usually use the same ancillary files as 34xx/35xx which means using the split-screen 212*234 picture size jcv which of course isn't available to this non-unicode map.

    You're saying quite plainly that the 480*270 is displaying in the KW as a splitscreen view as exampled by the lower pic from the internet. Could you be more specific as to how it's showing? i.e. is it shrunk proportionally to display the entire image, or is the image cropped back? e.g.:

    (1) [Only registered and activated users can see links. ] or (2) [Only registered and activated users can see links. ]

    The above are 212*234 (1) shrunk and (2) cropped proportional representations of this full screen 480*270 image from EU 2015.20:

    [Only registered and activated users can see links. ] [Only registered and activated users can see links. ]

    My experience with a nuvi 3590 loaded with non-U EU and full screen 480*270 jcv result in this (simulating a route on M6 to Manchester in UK):

    [Only registered and activated users can see links. ] However, the unit gets a little confused when scrolling thru the route because when it shows the immediate next jc view it shows as split screen, but then subsequent upcoming views on scrolling show full screen:

    First this: 448501 Then this: 450172

    Thatís correct i am currently using this MAP & JCV file # D2504170A running from a SD Card on my DNX7230DAB & its displaying split screen junction views on simulation

    Think i am seeing images shrunk proportionally rather than images that are cropped back.


    Quick Question : Should i actually be using NTU Maps if you canít get 212*234 .JCV files for the NT maps

    Note : Also your attachments @ the bottom of post # 29 Attachment 112158 & Attachment 112159 are not showing up for me

    Update :

    2w1w4t0

    ^^ The above image is taken from the pre loaded 2013 maps the unit came with

    zuldtd

    ^^ This image is from the maps & jcv file from NT 2015.20 off the SD card
