Last month I successfully programmed some new (i.e. blank, purchased from Jepp) Garmin 430/420 cards with the Jepp Skybound datawriter flash programmer.
This month I tried to take the original two datacards (Cirrus/Garmin-supplied) and program them with the Mar 22 update, and the Skybound program complains about them not being the right type of datacard – I tried both types of datacard listed in the Skybound program, with no success.
I can still successfully reprogram the cards I bought from Jepp with the new data, but this foils my plan of having two datacards in the radios and two extras, ready to be programmed a few days in advance of the update changeover.
After waiting over 1 hour on hold for Jepp tech support and then giving up, I thought I would ask you guys – has anyone been able to reprogram the original datacards, that came with the radios when the plane was delivered? Or are they non-re-programmable? Is there some special trick to it?
I don’t see any part numbers on the cards that would differentiate the “blank” ones I bought from Jepp from the Garmin/Cirrus supplied ones.
Thanks in advance!
