How to install any Garmin map on Iphone Garmin StreetPilot

**KikyK** · 25th January 2015, 06:08 PM

Hello everyone!
I have tried to add a custom map to Garmin W. Europe 2.9.1 (on iPad mini with iOS 8.1.2) by combining/joining it with the downloaded one in the program.
So far I have had no luck with that, but a funny thing popped during the process.
When I tried and joined the two maps with "GMapTool", I uploaded them to the Documents folder, replaced the original "img" file and the program recognized the map as the downloaded one and it did not delete it, requesting for a new map download, but strangely it did not show it when I tried to view the map, neither my local map or the original Garmin map.
After this has happened I deleted the local map that I have added to the file along with most of the other maps leaving only a part of the map of Greece and I uploaded the same file back to the iPad.
This time when I tried to view the map it showed the map of Greece I have left with streets and everything.
So I came to the conclusion that maps are editable.
And also that the reason I did not succeed in the first place is because I could not change the FID and CP of the local map with "GMapTool" and mach it with the one of the CN 2015.20 Greece & Italy that I have downloaded with Garmin.
I have also tried other software, but none seems to do the trick.
I am open to ideas and if any of you think that this might work, lets try to get the newer versions of Garmin working with custom maps.

You cant edit a Garmin NT .img
You can edit non NT and "Pseudo NT" maps.
There is a thread for this:

Are the files from android street pilot compatible to iphone street pilot like the voices and maps?

All working well here but I have a few questions / issues (IOS 8.4)

1. The navigation voice fades out before the direction is completed
2. Safety camera alerts "on with audio" graphics are working (icon is shown on screen) but no sound is made

Is there a way to rectify the above 2 issues

Hi All,

I'm hoping to get Garmin working on an elderly iPhone 3GS. Can anyone PM me a suggested location for v2.2?

I have 2.7 but it comes up with the map management window and Garmin no longer provide the files (so it's stuck on 0%). I'd prefer the older .System method to be honest.

Regards,

Alex

Hopefully this post is still alive.
I have a very weird problem. I successfully installed Garmin USA Version 2.0.19 on my jailbroken iPhone 4s with ios 6.1.3. I also successfully added North America unlocked maps 2022.20 along with JCV (full screen) files. All is working great.
The only issue I have is that the arrival time on app is off by 1 hour and 36 min from my iPhone time. It remains off by same all the time. Looks like gps time is not being synced with iPhone time.
Any ideas from experts? I have iFile installed and have looked over all plist files for any clues but I'm stumped and this is very annoying issue. Garmin time does progress but remains behind by 1 hr and 36 min exactly.

@skumarnuvi
Wrong time display can be caused by not using the latest version gmaptz.img or not having it present in .System.

Thank you so much @Butters
Yes that was the reason. I copied the latest version of gmaptz.img in the .System folder and restarted the app and it corrected the time issue. Its working great now.
Although I had to delete the gmaptz.img afterward because it was not letting the actual map file (gmapprom.img) to render (possibly due to same .img extension). Anyhow, even after deleting gmaptz file time is all fixed now and I'm a happy camper

@skumarnuvi,

I do not know why you would have problems with img files.

Under .system folder you have:
gmapprom.img
gmaptz.img
gmapbmap.img

They all have the ending of "img"
So there is no need to remove gmaptz.img. The gmapprom.img will work just fine.
You then have other problems when the gmapprom.img map does not show it has nothing to do with gmaptz.img

@asprin624 i get what you are saying and that's how it should work but I downloaded the garmin ipa ver 2.0.19 that is on the first page of this forum.
after installation my .system folder was empty. So I copied the gmapprom.img (which is 2022.20 unlocked maps) and a couple of JCV files in single folder named JCV. So my .system has a JCV folder and gmapprom.img file only.
There is no gmapbmap.img file. May be whoever repacked the ipa may have done something to integrate the basemaps but I don't have that file.
Prior to copying gmaptz.img file I had the issue of 2 hr behind time with the app but after copying it resolved the issue. But app was not rendering the map so I removed the gmaptz.img file from .system folder and it is working fine.

Will try and play more to see why this is happening but on my end .system folder is not liking more than 1 .img files. Would love to hear more about this

my .system folder was empty upon installation and when I copy more than one .img file it don't render the map.
