Re: Garmin GPS to PPC serial connection

Tech-Archive recommends: Speed Up your PC by fixing your registry

Are you here in the USA? I'm curious as to how you are making the connection between the Garmin and the PPC6600. Can you include the part numbers? Does your cable from the Garmin plug directly into the cable from the PPC6600? I'm asking because I believe that from what you've posted it does. I believe your first step is installing software that will allow you to look at the serial stream from the Garmin, just to verify you are attempting to use the correct port. And you are actually getting data to the PPC6600.

Garmin GPS's have a Garmin proprietary protocol (or several, over the
years!) which can include a Protocol Array packet which tells the
communicating program which parts of the full protocol that particular GPS
is capable of. If the GPS does not deliver the Protocol Array packet then
the program is expected to look up the device code in an internal table
which tells it the same information. (This is mainly for older units, which
should therefore be in the table.) You can read this sort of thing on the
Garmin website or in USENET at sci.geo.satellite-nav.

I have no idea if the program concerned would deliver this message if the
GPS were set to send NMEA messages instead of the Garmin protocol. I would
expect it to detect this since it is such an easy mistake-a to-a make-a.

I will take a look at the info on the Protocol Array packet, but if that is
the problem I'm pretty sure it's beyond my capability to fix.

I tried NMEA protocol and all I got was a com timeout.

I'm beginning to suspect that this software doesn't like my PPC for some
reason. If someone knew of something that would upload and download tracks
to a Garmin 60C using an Audiovox PPC6600 I would get that.
