As others have noted, running a long wire is probably not going
to work well in a car. Another alternative to using the radio's
built-in antenna or finding the connections from your car's
antenna would be a small mag-mount whip with coax. (You can put
a bit of plastic wrap under the magnet to keep it from scratching
your car's paint.)

My car that now has the Becker Mexico is currently in the shop
while my mechanic tries to figure out why the seemingly solid
antenna connection is going in and out. In order to enjoy the
radio before it went into the shop, and to show him how the
radio should be performing, I put my 2m 1/4-wave whip on the
car and got an adapter to connect it to the Becker. It worked
like a dream. When I put the radio in scan mode after sunset,
it was stopping on a station nearly every 20-40KHz on shortwave.
Longwave and medium-wave reception were also excellent. So that
might be another option for you.

Enjoy your trip--and drive safely!
