Thread: Mapear and cGPSMapper Maps issue on Android Garmin Street Pilot 2.16-workaround

I can confirm the same bug with VENRUT (just like Mapear but from Venezuela). The APP crash when calculating a route. VENRUT also uses cGPSMapper Maps.

After several days (and nigths) testing, I think i found a workaround. It is NOT flawless but allow to use the APP without problems. Just in case is relevant, I'm using Android 4.1.1 (HTC One X AT&T STOCK -NO ROOT, NO BOOTLOADER UNLOCK, NO S-OFF-).

01. Download and install the APP (choose the one that fits your needs) from:
[Only registered and activated users can see links. ]

02. Download the BaseMap 5.01 and put the file (gmapbmap.img) in your storage card at "/Garmin /.System" The basemap can be found here:
[Only registered and activated users can see links. ]

03. Download the TimeZone Map 13.00 and put the file (gmaptz.img) in your storage card at "/Garmin /.System" The TimeZone Map can be found here:
[Only registered and activated users can see links. ]

04. Download City Navigator Sout America 2014.20, UNLOCK the IMGs, and put the files (gmapprom.img and gmap3d.img) in your storage card at "/Garmin /.System"
- City Navigator can be found here:
[Only registered and activated users can see links. ] (Download the FULL SAM. The 3d is not necesary but is so fancy)
- IMG Unlocker can be found here:
[Only registered and activated users can see links. ]

NOTE: Yeah, i know, i know, Mapear at Argentina (like VENRUT at Venezuela) has more detailed maps... Just wait a minute, take a deep breath and relax. You will use Mapear (or VENRUT)... Keep reading...

05. Download your favourite map (Mapear, VENRUT, etc), generate the IMG with MapSource or MapInstall, put the file (gmapsupp.img) in your storage card at "/Garmin /Map" NOTE: The Map folder (inside Garmin folder) does not exist and you have to create it... Just make sure DO NOT put at "/Garmin /Garmin"

That is it... Now, the explanation...

For an unkown reason, Mapear (as VENRUT) fails to calculate route. Also missed categories and some other bugs. I'm sure it is because the cGPSMapper.

When you put the City Navigator as gmapprom.img at /.System and Mapear (or VENRUT) as gmapsupp.img at /Map you create a hierarchy. As you already know, gmapbmap.img (basemap) is the first map the APP check for routing, the it checks the gmapprom.img (City Navigator) and finally it checks gmapsupp.img (Mapear or VENRUT). The APP does not fails routing because City Navigator tells how to do it and Mapear (or VENRUT) just indicates the details of the route.

I already tested. It does not fail. It routes to anywhere, short or large distance... You will have the Categories back, Gas stations, POIs, all the Mapear (or VENRUT) stuffs... You can search, browse, do whatever you want.

But this method has a fail... While you are driving (after calculate a route), you can not see the coloured path that indicates the right road... It is because you are using two maps with the same route at the same time...

You MUST use both, City Navigator and Mapear (or VENRUT), at the same time in order to search, browse categories, calculate a route, etc... When a route is calculated you MUST deselect City Navigator Map in order to see the coloured path that indicates the right road.

You should reselect City Navigator Map every time you need to search, browse and route...

Yeah, is a crappy workaroud but it works for me.

Hope this helps..!

PS: Sorry for my poor english.

Hi, thanks for your post. I'm trying to set up like you describe so I can use the VENRUT maps, I have one -I hope- "dumb" question since I'm kind of new into this. When you say:

05. Download your favourite map (Mapear, VENRUT, etc), generate the IMG with MapSource or MapInstall, put the file (gmapsupp.img) in your storage card at "/Garmin /Map" NOTE: The Map folder (inside Garmin folder) does not exist and you have to create it... Just make sure DO NOT put at "/Garmin /Garmin"

How can I generate the gmapsupp.img file? I have installed MapSource and another program called IMG2GPS, the second is very easy to use but I don't know if I have to select all the files of the VENRUT. Here goes a picture so you can follow me better:

[Only registered and activated users can see links. ]

So as you can see in the image, there are all the img's for the zones and then there are those 3 last files:
-Venrut.img
-Venrut.TYP
-Venrut_mdr.in

My question is, do I have to select them all or just the img's? or if you could explain to me how to do it with MapSource I'll be much grateful.

So thanks again, excellent post. I'll give it a try this way, if it doesn't work I'll know that it was because of the gmapsupp.img.

This Workaround can work.... But I think the problem is with cGPSmapper you are using to create the map..... Free cGPS mapper dosent support routing, POI, City Indexing etc.... Basically it can only make custom IMG. The IMG created has routing information but it is broken(intentionally) by Free cGPSmapper. Try using a commercial one.... I used that to create Asian maps and it works!!!

Good Day

I have tried your solution again.

And yes it works. Still, it is too complex to use. If it does not need to recalculate one can set the route and then disable the CN map (if not, the route is not visible at all scales) so the real Mapear (or Venrut) layer can be seen and the route is displayed.

but as soon as it has to recalculate it will crash

Think it should be made clear what this means: It is only an 'optical' Workaround... meaning the routing is totally based on CN streets und you only see the other map, not more. Any streets, ways and paths included in the 'problematic map' are not used for any routing... so it's at least not a workaround, if somebody needs the e.g. offroad streets of the problem-map for routing...

I justed tested it for CN Europe and some 'problematic' OSM-based maps... you see the nice OSM-maps, but they play no role for the routing...'

By the way: even if all maps are 'activated' you see a) the OSM map and b) the route itself... so no need to deactivate CN...

I'd already seem all the video tutorials from the gpsyv website and anyone solved my doubt. Earlier I found here on the forum a post where someone had what I needed.
Thanks anyway!

Hi, does anyone knows why I can't search by address? The map shows them, but if I search by address nothing comes out

Thanks!
