The LX web site says that I can use the MIni-map kb with my LX 5000.
It is somewhat pricey at $ 1600 with Seeyou mobile at twice the price

Anyone has use it and care to comment.

I saw the LX Mini Map yesterday at a conference, and I compared it to
my Altair (which Triadis donated to me for XCSoar development) - the
Altair has the brightest display I had seen so far, which makes it a
good reference.

LX Navigation Germany showed it side-by-side with an old iPaq, but
they configured a low brightness on the iPaq, which seemed like an
unfair trick to misguide potential customers.

Initially, the LX Mini Map looked a lot brighter than my Altair, but
it turned out the Altair dims down when its light sensor reports low
environment brightness, while the LX Mini Map was always at 100%. *May
be another trick to get potential customers to say "wow". *After we
pointed a flashlight at Altair's sensor, it became a lot brighter, and
in the end, both looked the same. *There was no direct sunlight in the
hall, but it is safe to assume that the LX does as well as the Altair.

The Altair's screen resolution is 320x240, while the LX has 800x480.
Naturally, the LX can show more details, which is very convenient.
And it has a touch screen, something the Altair lacks.

Technically, the LX is just a PDA with a better display (very bright
LED backlight).

After I inserted my own SD card, I could launch XCSoar 6.0, works like
any other PDA/PNA, as expected.

Max,

Sunlight readabilty of displays has less to do with brightness (nits)
than other factors.
The more important factors are coatings (two different are required
for excellent sun readability), contrast ratio, touch overlay or lack
of, size and screen resolution.

I have seen the following displays and made comparisons in direct
sunlight IMHO the viewabiltiy from best to least below:

Craggy Aero Ultimate
LX9000
ClearNav
Altair
LX8000
LX MiniMap
Oudie
HP4700
HP 310
Ipaqs

You will notice that the displays without touch screen overlays are
all on the top of the list.

The Ultimate is the most viewable as it has 2 coatings, no touch
overlay, high contrast ratio, vga resolution, largest screen size and
the brightest backlight (nits).
