Same thing here. As I was comming home my display was dimmed to where normally 80% would be even though I always have it at 100%. I stopped for gas and could only bear to put $5 before my hands froze. When I started up my car the display looked like it was at 0%-$10. I removed my empeg and put it back in and it went back to 100%. I thought it was the temperature but the empeg wasn't too cold. I tried playing with the dimmer but 60% would sometimes be brighter then 80% and somtimes 80% would be brigher then 100%, all randomly.
Anyone know whats going on?
