I am on my 6th repair. Actually, this time they gave me a
reconditioned unit, as mine has been repaired so many times. I have
always been told it is not a porblem with the monitor itself. I first
began getting colorful vertical stripes when my unit was about a month
old. I was getting at least 50 and sometimes way more than that, so
that it was hard to see the display. I sent it back and they said it
was all taken care off. It did work better for a few months, but then
the stripes reappeared. I sent it back again and and it came back
working fine for a few months. The third time it went back a fan was
installed. That worked for several months, then the stripes came back
again. The fourth time I was getting pretty mad. I was told they were
going to replace some faulty part they discovered. The fifth time,
Garmin AT had taken over. They assured me their repair would do the
trick. The sixth time, I said enough already. I want a different
unit. I was expecting a new unit, not a reconditioned one. My plane
is just coming out of annual so I haven't flown with the
new/reconditioned unit. With it historically taking a few months to
show the stripes, if it is going to do it again, it will be later this
spring. Every repair has been under warranty and Apollo and Garmin AT
have been kind and easy to deal with. But it is very frustrating to
shell out lots of $$$ for the unit and have this repeatedly happen. No
one there said anything ever, in all my conversations with them, about
the unit expected to last only 18 months.
