wrong...do not add any external antenna...the s80's is built in
or hidden and works fine once hooked up and grounded right...
go to another dealer, and report your current dealer to volvo
corp...and..let
us all know so we don't take our volvos to the flakey dealer...do some
searching on the consumer reports / auto recall web sites, or do a car
fax ($15) on your volvo & vin and you will get a print out of the
nation wide
recall and fix for the poor am reception on all s80's...then you will
have
the recall/fix tec number and something in hand to show the dealer...
i would not let some clown install a "outside" antenna on my s80....
good luck !! keep us posted...
