Apart from being horrible slow to resume 2 - 3 second compared to the 1030. Auto pause does 2 additional things;
1) it places as pause icon on the screen, and it dims the screen making it very hard to read. if you want screen saver to save battery which i understand make it configurable. i don't want it as every set of traffic lights. slow resume means a dimmed screen that is hardly readable for 2 - 3 seconds
2) it stops the 1040 from responding to the Di2 buttons. scenario. I come the the trafic lights, stop and want a quick look at the map, pause is on and i can change screen. Use my right hand to switch pause off , and it's back on by the time i reach the di2 button - almost immediately Grrr......
I wonder what else it does?
