Fair Enough
Brantel, fair enough comment. Experience is a good measure of value.
I have an A200 in the panel and the metal catch stopped working (hex head stripped, I think) so it could not be secured in its tray. At that point I decided to upgrade to A210 while repairing the A200 & selling it.
The A210 worked fine, great display, & no issues with ribbon cable. Next day, fired-up the avionics and the A210 display was dark - the freqs worked. ICOM support told me to remove / reinstall the ribbon cable; I did, no display.
Repaired the A200 metal catch & reinstalled it; it worked fine. Reinstalled the A210, display dark, called ICOM support, they told me to replace the ribbon cable. Even a new cable does not guarantee the display will light in the future. Losing confidence in the A210, I exchanged it for a GTR-200. For now, the A200 is in the panel until I can re-pin for the GTR-200.
My experience may be anomolous, but the A210's display situation & the ribbon cable design cause me great concern; the ribbon cable was livable, but not the dark display (ever!).
Safety-wise (IFR panel) I prefer a second radio that has a contemporary electronics design, gives an easily readable display, and is well-supported.
