How to install any Garmin map on Iphone Garmin StreetPilot

@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.

@skumarnuvi
It is possible for a Garmin device or app to work to some degree without a basemap (gmapbmap.img) however there will be times when the software switches from the primary mapping to the (lesser detailed) basemap. If the basemap is not present then the software will freeze or cause the hardware to re-boot. For example, basemap use is necessary when zoomed out and scrolling.

You should add a basemap, various versions are available in different sizes and coverage, with and without DEM. The most recent fully featured world-wide basemap is Version 6, you can obtain one here: [Only registered and activated users can see links. ].

I endorse what asprin624 stated regarding the timezone map not likely to interfere with the detail map and there would have been some other reason for that rendering problem.

@Butters and @asprin624. Thank you both for helping out.
Yes I put in the basemap.img and gmaptz.img again in the .system folder and it is working fine (no issues so far).
Is there a way to keep 2 separate maps in the .system folder?

All Garmin products are the same when it comes to maps and their locations.
Please take the time to read other posts when it comes to Garmin stand alone units.
All the info is there as to where to place other maps.
