Dear experts:

Facts:

* Garmin Nuvi 50 LM with OpenMapChest 2017.10.18 in memory card and City Navigator North America 2018.30 in unit
* Garmin Nuvi 57 with OpenMapChest 2017.10.18 (map in memory card, only this map installed)
* Garmin Nuvi 67 with OpenMapChest 2017.10.18 (map in memory card, only this map installed)
* All units with the latest Garmin upgrades
* Route tested: LAX Airport (CA) to San Luis Obispo City (CA)
* Same navigation preferences and avoidances in the three units (faster time, U-Turns, Carpool Lanes, Unpaved Roads)
* GPS in simulation mode

In the three units I uploaded the same POI file, using Garmin POI Loader software.

I used those loaded POI to test a route between LAX Airport to San Luis Obispo City.

The point I uploaded for LAX Airport is: 33.95471807,-118.37625028,"Alamo LAX Airport"

The point I uploaded for San Luis Obispo City is: 35.32737742,-120.72593977,"San Luis Obispo"

In the Nuvi 50 the map selected is the OpenMapChest; the route and distance is correctly displayed. In the Nuvi 57 and Nuvi 67 they show a completely wrong route (going southeast first, making the trip around 7 hours longer). Please see attached links.

If I insert the memory card of the Nuvi 57 or the Nuvi 67 in the Nuvi 50, and select the OpenMapChest map ¡¡the route is displayed correctly on this unit!!

If I manually enter the address of origin and destination; the same wrong behavior is shown in the Nuvi 57 and 67 units. I could not duplicate this issue using any other pair of origin/destination. (all the other routes tested are ok.)
