Gary's email to me:

Hi Dan,

I was browsing rec.aviation.soaring and read about your troubles with the
302 polarization. Unfortunately it is the LCD that is polarized and not the
window glass.

As I recall, in the early production days of the 302 the first batch of LCD’s
received were not polarized correctly and nobody at CAI noticed. Once the
complaints started rolling in, the manufacturer was notified and further
shipments of the LCD’s were polarized properly. I suspect you have a very
early instrument?

In regards to replacing the LCD with the newer polarized glass, we (ClearNav
Instruments) are looking into purchasing some of Cambridge’s inventory so we
can go forward with support of the 300 Series.

Stay tuned…….

Best Regards,

Gary

I may have read the http://clearnav.net/main/cn-service.html page wrong but
it appears they only service the older Cambridge products.

GPS-NAV™ Datalogger
GPS-NAV™ Display
L-NAV™ Glide Computer
S-NAV™ Glide Computer
CAVII™ Variometer

Probably because they use discrete components (individual resistors,
capitors, transitors, etc) or single technology ICs which they can easily
troubleshoot. Not so the 302.
