My Vapirius has an interesting problem that appears to be memory related.  
 
When I run either Sygic or iGO Primo sat nav apps, they start and run for a few minutes, but then shut down.  
 
This occurs whether the apps are installed on SD card (32GB Class 10) or internal memory. I have stripped the watch down to almost zero apps and I only see Google core services running. Cleaned out cache and all the useless data. There is over 100MB free!  
 
The watch is also rooted.
 
I'm thinking that may be the GPS isn't getting a lock fast enough, so I tried Active GPS app and a few other GPS enablers to get a quicker lock. Perhaps this is the cause?  Checked the GPS settings in the system folder and all normal.  
 
Every other app runs perfectly.  
 
GPS? Memory?
 
HELP!!

Sorted!  
 
GPS was timing out. In fact sometime never got a lock at all.
 
Now the GPS is running well. Changed the system/etc/gps.conf  file to this (for the UK):
 
 
NTP_SERVER=0.europe.pool.ntp.org
NTP_SERVER=1.europe.pool.ntp.org

I'm currently running iGO Primo (my fave), Sygic and CoPilot Live Premium.
