I've been using my flight deck computer for several seasons and it works great, (until now) and I love it. It is an older model, 7-8-9 speed only (not 10 speed compatible).
At the beginning of this season, I reset all functions so I could set the odometer at 0 to chart my season distance as I do every year. I re-programmed everything that needed to be reprogrammed (gears, tire size, time of day, etc).
I reinstalled the computer onto the mount. Now the only functions I get are:
time of day is correct
odometer logs cumulative miles accurately
cadence is accurate
speed is accurate.
I don't get any "trip" functions - they all stay at zero.
etc. all stay at zero.
All of these functions used to work and would continue to log between rides unless I re-set to 0 by pressing both R and L buttons. I've tried doing this, but the all 0's continues.
Both left and right buttons on the shifter hoods work - I can scroll through the functions and modes and actually start, stop and reset the stopwatch.
Obviously, the computer is working and picking up the wheel magnet because like I said it's giving me speed and cadence and the odometer advances properly.
What have I done wrong? I skimmed through my owner's manual, but nothing caught my eye. I'll study it more unless someone here has a pointer. My guess is that my correct response will be "DUH!".
