My concern is where it states the following even before it talks about which
GPS units can be connected:

"HARDWARE

EWFR models A, B, C and D. These are IGC-approved only when connected by
cable to the specific GPS units listed
below. All models have a 9-pin 17mm wide female connector on an end face.
This has EW-proprietary pin
connections (see 1.1.1 and 1.1.2 for connector cables). (AL 1)

Models A, B and C. Versions or upgrades must have dates of May 1997 or
later. Model A has an altitude capability
of 10km., model B, 12 km., model C, 15 km. All three models are the same
size, approximately 150 x 80 x 30 mm;
weight is about 270 grammes. A 16-button keypad (about 60 x 60mm) and LCD
(about 50 x 200mm) are on the front
face."

Since I have a GPS 90 that I can use it would be great if it turns out that
the firmware version is only a factor in which GPS is allowed.

The answer lies in the latest Approval Document which can be found on
the FAI website. The URL is:
http://www.fai.org/gliding/system/files?file=ew.pdf

where it says:

"EW firmware 97XX or later may be used with the following GPS units:
Garmin GPS 12 XL, 80-Mil, 89, 90 and 95, and the Garmin GPS 55 with
software versions 1.12 or later.

EW firmware 98XX or later may be used with the GPS units above under
97XX, and also with the following: Garmin GPS II, II plus, III, III
pilot, IIIPlus, 12, 12CX, 48, 92. Also the Garmin eTrex, eMap, GPSCOM
190, GPSMAP 195 and 295. (AL3)"

The early firmware version limits the Garmin GPS engines that may be
used.
