What about the temperature ?

The temperatures on my 1040 are at least as inaccurate as my 1030+, maybe just a little worse. Tech support told me the 1030+ temperatures were “by design”. Shame on Garmin.

My impression from the first excursion with the 1040 is that the temperatures might be nearer the truth than on the 1030. I concluded that Garmin deducted 3C from the measured temperature on the 1030 to try to compensate for heating in the sunshine which, of course, results in 3C low temperatures when the sun isn't shining. It's possible that Garmin put the 1040's temperature sensor where it is least vulnerate to heating from the sunshine.

If you want more accurate temperatures then a work-around is to fit a Garmin Tempe temperature sensor somewhere on the bike where it is exposed to passing air but affected by direct sunshine or radiation from a hot road surface (proper weather stations have thermal shielding). However, an app to read the Tempe data (eg Tempe Visualizer) isn't currently available for the 1040.

On my 70 min. ride today I had a 1040 and 1000 mounted on my bike. The sky was partly cloudy. Much of the ride was in the open but some was shaded. As calculated by Garmin Connect the 1040 read an average of 6.7F higher than the 1000. This typical of the difference I get between the 1030+ and the 1000. The 1000 typically reads a  degree or two higher than the actual temperature. If Garmin could get it right with the 1000 (and the 800 before that) why didn't they get it right with the 1030+ and the 1040?

I'll compare the 1040 and the Tempe on my next ride although, as the Tempe is on the underside of the stem (shielded from sun and open to wind) it is vulnerable to radiation from a hot road.

I've always assumed that the metal plate on the underside of the 1000 has the temperature sensor attached to it. With the 1030/1040 series, Garmin went cheapskate and didn't bother with this. The sensor in the 1000 certainly responds to temperature changes a lot more rapidly than the sensor in my 1030+ or my wife's 1030.

Garmin also went cheapskate with the cases on the 1030/1040. When the battery in the 1000 needs replacing (which I've done twice since I bought it about eight years ago), the case comes apart by undoing six Torx screws, and the two halves are sealed together with a gasket. On the later models, you need a heat gun and prising tool to get it apart, and are then faced with the problem of holding it together and waterproofing it properly on reassembly.

I'm surprised your Edge 1000 lasted that long.  The buttons failed on mine after about 10,000 miles of use.  Never realized the temperatures were so far off on the new units.  I did notice that the Edge 1030 (and Edge 1030 Plus) seem to read insanely high if you don't park your bike in the shade.

I've had to repair the power button - they're notorious for failing on the 1000 - the plastic covering is too thin and splits. The other lap and start/stop activity buttons have been fine.

I used one of these to repair the power button: https://www.ebay.com.au/itm/124405186250.

i find if you look at the "real feel" temperatures in your area, Garmins are always pretty close to these, rather than the forecast temps which are recorded in the shade

Really? The "feels like" temperature is usually lower than the actual shade temperature. e.g. This morning when I climbed on the bike, it was -2.3°C with an apparent temp of -4.6°C, at 2pm with the sun out, the corresponding values were 8.5°C and 4.5°C, and at the moment (9pm) the real temperature is 3°C, but apparent temp -0.5°C. My Garmin always indicates several degrees higher than the real temperature, so it's even more inaccurate as regards the "feels like" temperature.
