Ah, yeah, that too. :-) My eTrex Vista HCx definitely does the USB Storage thing when I plug it into my PC, and I've searched around all the docs, and it is only got a USB slave/client/whatever. No host mode, and no RS-232 Serial buried on secret pins.<br><br>I bought it knowing all this, hence the GPS board hanging off my Kenwood TH-D7...<br>http://home.wavecable.com/~ko6th/IMG_0235b.jpg<br><br>Greg KO6TH<br><br><br>> Date: Tue, 17 Feb 2009 20:34:19 -0800<br>> From: scott@opentrac.org<br>> To: aprssig@tapr.org<br>> Subject: Re: [aprssig] gps/tnc linkup<br>> <br>> If all the handhelds have is USB, then no, this won't work.
