Thread: CityXplorer maps unlocked to work in Nuvis 37xx series

@catymag
Thanks for explaining, got it to work.
Created unlock file for the wrong map, not the 3D map but rather the City Explorer map.

The gmap3d.img was also copied to the system folder, this map does not appear.

I am not sure which map needs the unlock key, I assume it's the gmap3D.img.
Used the jetmouse KG with checksum and generated key for Map ID 800, named it gmap3d.unl put in System folder, but map does not appear.
Tried renaming the file gmapprom1.unl thinking the main map needs to be unlocked, that still doesn't let the 3D map appear.
This map must appear for the enhanced pedestrian feature to work, according to Garmin this feature works on the 1350T.

Can somebody please explain what I did wrong.

3D map for buildings do not supported by all Nuvi 1xxx (inc. 1350T) in any mode, auto or pedestrain!!! See Garmin specification for your device in detail or owner manual attentively...

Some weeks back i loaded New York and paris with NO problems on sd card (3790T)
However, the Australian cities ie: Melbourne and others, will not show up on nuvi no matter what i try, incluing running unlock software we use. Has anyone had any issue??
Also to note. Melbourne Navetq has sensis map , i think this is error by uploader.
Thanks

@catymag,
Why is there no problem when i extract the paris map, it has the unl files for both imgand 3d extracted. BUT for instance the Melbourne or sydney or adelaide maps etc have ONLY img map and thats it. Usually the unlock map with have unlock/locked folder for you and place it on sd and works. I have had very littlel problems with other maps using simple unlock sotware.
Im i missing the point? If the maps are Unlocked we should be able to extract and place in the sd card.
...Melbourne Navteq folder wthen extracted will show the navteq 3d map but the img map is "sensis" you may want to check it out.
Also i have fround this site so demanding on other software with jetmouses and so on when simple unlockers work fine, why bother? and chance at least "clear" details what to use instead of frigging around like im doing now. remember the paris worked and extracted great , but all the new ones seem to have issues as you said with unl file, that i cant find when extracted.
Hope it makes sense to you.

@catymag
Just to confirm what issues i have... the Melbourne.Navteq file has a folder with 2 files. 1. is melbourne.sensis.img and other is
Melbourne.navteq.3d img...there is NO navteq img file? Whilst the Melbourne.sensis has exact file as in the navteq folder.
Now for the big problem.... i have spent a great number of hours trying to work out all the posts i can workout how to make a "unl" file. Unfortunately im stumped, i have opened up many other maps and had NO issues with NJ and Paris that has been posted here. Only issues with all the Australian xplorer maps.
Here is what i have . 3790T
I have Jetmouse 1.5...I enter the unit id from garmin found in "about" .
then select software product in jetmouse is only XT....in select map product <custom mapset> ...generated map unlock code....
NOW here is where all the confusion is....could you PLEASE explain in more and simple detail as you would for someone who has no idea (me) as i have tried to work out with all posts in forums. Also can you confirm please are all the xplorer IMG maps "unlocked" and that there is nothing you need to do with the maps, reason why, i found one post where how to "unlock a unlocked" img map, so i would just need confrimation after extracting the map file that there is nothing else needed to explorer img map or does it still need to be tampered with?
Thanks again, i hope we can get to the end of this confusion and if i have sucsess i will post my version of how to do this as many have asked and asked again and always refered to some other post.
Thanks
