Default JB4 keeps resetting/rebooting while driving - 11-30-2016, 01:59 PM

Hello all, i am having an issue with my JB4 unit where it seems to reset or reboot while i'm driving and defaults to Map 4. I'll have it set to Map 5 usually and after some time driving i notice my flashers flash twice and when i check the JB4 interface on my phone its showing me that it is now in map 4 and has reset itself... Any idea whats going on? I am running the JB4 as ISO.

Have a JB4 log so we can see firmware, settings, model?
