I'm hoping that Garmin are taking an interest in our feedback in these threads with the Varia being so new.
So what I'd like to see is the battery level indication you get when you turn the Varia radar on (i.e. the number of LEDs that momentarily light up depending on battery strength) also being duplicated when you turn the unit off. It would be great if I was able to quickly see if I was going to need to charge the unit up before my ride on the next day. It's good to get this when you turn the unit on, but by then it's a bit late if you realise it's low.
