Kobo Aura refresh rate?

Nope - battery at 90+ percent. Like I said, the Googlesphere suggests that some versions (maybe early production) of Kobo were prone to washing out and becoming unresponsive in direct sunlight. FWIW, a highly sophisticated heat shield (i.e. a piece of cardboard box taped over the Kobo) seems to have eliminated the problem.

A somewhat related question - has anyone run into problems with a Kobo (Kobo Mini) washing out in direct sunlight due to overheating? I flew with one for the first time in a club glider earlier this month running TopHat on a Kobo Mini. The Kobo was secured via a suction mount to the canopy. I liked it quite a bit, until the display began to become fainter and fainter. At some point, the touch screen became unresponsive. Luckily, I had a backup copy running on my HTC One which worked fine.

Some Googling suggests that some Kobo Minis may have issues with long periods in direct sunlight. Anyone in the gliding community care to comment?

This might have been a low battery problem rather than a screen heat issue. If the battery is at it's end the Kobo will screen freeze and nothing works after that.

Hi, for those of you that used Kobo Mini, what GPS do you suggest and how difficult is to connect to Kobo?
Thank you in advance,
Sergio

Sergio I haven't yet had a Kobo to try this on but my best information points to this plan:

.. Run XCSoar on a Kobo. Set it up to receive GPS data by TCP over a wifi link. I've tested this so I know XCSoar can do it.
.. Run an app called BlueNMEA on my Samsung Galaxy S2. This apparently lets you output GPS signal over wifi. I haven't tested this part.
.. Have a portable battery available in the cockpit to charge the S2 (or the Kobo) via usb if it runs out of power... though I'm expecting it to last at least 2 hours because the screen can stay off.

Oh also... I plan to test this on the the ground first as I've had problems in the past with radio interference from setups like this (specifically with the USB charging). If someone who knows about such things can tell us all how best to avoid that problem, I for one would be grateful.

I'm a diehard Kobo/top hat fan.
If you haven't used an ereader screen in a glider, you are in for a treat.

I just replaced my first kobo (left other in rental car )
and my new (old stock) kobo has the sunlight issue. It's becoming very light during the flight to almost unreadable. This is especially bad with high temperatures. I did not have this problem with my previous kobo so I think this is a QC issue.

I have my kobo wired (soldered) to a colibri II. This is an amazing setup that gives you everything you need from a moving map + IGC approval for badge/comp/record flying. The kobo charges the colibri and the whole unit is charged from a micro USB.

I have noticed the radio inference if I hold this unit close to my Dittel radio, doesn't effect it unless I hold it close though so it's a non issue for the most part.

Glad I wasn't the only one with the sunlight issue. I've built a temporary shade out of black cardboard. I'll test this out a few more times before claiming victory, but it seemed to help a lot in the two flights where I used the prototype version (i.e. the top of a box taped to the mount with wing tape).
