Have been using the RAM yoke mount for a while now. It's pretty flexible so you can angle it however you want (closer / further from you) it takes a bit of fiddling so you would want to have a spare 15 minutes to mess around with positioning. The standard kit comes with adapters to mount it to the glare shield as well (flat adapters so it does not damage the surface).
You can also get them on
eBay from time to time although there's only two at the moment it would seem (
1 2).
So far no major issues with sunlight etc. Have been running it at full brightness and using it as a backup to maps, etc. So far I've been using Air Nav Pro but as soon as Oz runways has multipoint routes then I'll be making the switch. Air Nav seems to crash a lot and it does not seem to have anywhere close the the information available in Oz Runways (waypoints, etc.)
