hi, I am (optically) disturbed by this cheap rubber antenna on the right at the rear. much more elegant, for the washing system also practical and also vandalism-safer would be an automatically exiting and entering electric antenna. Such there is from 40 Euro e.g. also Ebay. Has one of you already installed one? Does this work out in space? And above all: is there a cable in the trunk that leads electricity when the radio is one??? many DANK for information!!
