My map stop to load by Garmin

Hello,

I encountered strange behavior of my Garmin 78.
I used my custom map happily for a while, but it stopped load in one moment ( unit get stucked in one moment of starting). When I removed SD card unit started normally.
I thought that SD card can be corrupted ... I used new one and loaded same file but again unit get stucked.

Any idea what might be wrong?

thanks

mira

Re: My map stop to load by Garmin

Batterries almost empty? My Oregon sometimes doesn't boot when the batterries are weak and many maps are on the memory cards.
What about downloading fresh data and creating the map anew? It is true that maps may contain structures which the device does not like (I got a memory full error after some time using a broken map).

Hmm ... I used for first time eneloop rechargeable batteries ... I used setting NiMH for them in unit and they have been in good shape.

My Oregon sometimes doesn't boot when the batterries are weak and many maps are on the memory cards.

I always use only one map.

What about downloading fresh data and creating the map anew?

I created new map and removed some mkgmap options which I used for first time and was not sure if they can cause problem ...

--reduce-point-density=3
--reduce-point-density-polygon=8
--merge-lines
--min-size-polygon=10
--ignore-maxspeeds
--ignore-osm-bounds

Can these options be problematic?

It is true that maps may contain structures which the device does not like (I got a memory full error after some time using a broken map).

Is there any chance to make some system reset in this situations? I am going for some 6 week trip ... would be bad if my unit stop to work in middle of it

regards

mira
