Hi,

really a new idea :-)

It is possible to use the NMEA output of the Garmin 430/530 as an input
for a PC.

It is NOT possible to up-/download flightplans or waypoints.
This is NOT a technical problem.

It seems that it is not allowed for IFR or installed GPS-systems to get
Flightplans or waypoints via an external device.

There is only one chance to feed a Garmin 430/530 legally... with
another Garmin 430/530 via Crossfill.

Solution would be: write a program that simulates the communication
between two Garmins 430/530 and feed this program with flightplans and
waypoints from a flightplaning program or handheld GPS-systems.

Than you could up-/download flightplans and waypoints.
I would be happy to get such a software but writing it it is not a way
to get rich :-)

Another solution is a VFR only GPS like the KMD150. Here you can
up-/downlaod waypoints and flightplans.

Regards
Maik

PS: If I wrote anything stupid please correct me asap. thx.

Hi,

It seems most handheld GPS can be connected to a computer (through a serial
cable, IIRC).
That allows some cool features, like preparing your flightplan in advance on
your PC, or downloading to the PC the actual positions of your aircraft in
order to obtain a chart of the actual flight path.
Now, do you know if panel-mounted GPS can also be connected to a PC ? Namely
for Garmin's GNS 530 ?
I can't see any reference to this on the 530 reference manual, and I would
be surprise that handheld GPS can do thing that Garmin's top tier GPS can't.
