Quick report: The maps generated with the latest mkgmap work quite nicely with the ancient Vista device Thanks Gerd for the recent patches to shrink maps further And thanks to Greg for pointing me towards "sendmap", which worked Jakob Am 11.09.2016 um 02:10 schrieb Greg Troxel:

sorry to ask this here, but I have a device question. Does someone here use an ancient eTrex Vista (non c, non cx, non Hcx), and knows if mkgmap files can be transferred via serial port and be used on it? All information is highly welcome I'm not sure if I'm being duplicative because my German is not so good (understatement!).
I know of two ways to transfer maps to a serial port garmin. There is a program "sendmap" floating around, and I have only seen a binary for Linux. Also, Garmin's mapinstall/mapmanager/basecamp (or roadtrip) can do this, installing subsets of the map after you have loaded it.
For the second way, on a mac
use gmapibuilder to make a GMAPI format from the img
open the gmapi to use mapinstall
open manmanager and click a lot until you figure it out
for sendmap:
find a sendmap binary
make an IMG
run sendmail with the img and the serial port
figure out the limit on IMG size
repeat
however, keep in mind that an etrex vista, not HC, probably has a very small area for maps. I had a GPS V that could do maps but not really load a big area (20 MB?), and that was with the proprietary data that had only roads and POIs, not what OSM has.
So I do not think you are going to end up being happy....
