A: Poor Radio Reception on 325i?
I don't know what year BMW switched, but my 1999 323i radio antenna was embedded in the rear window glass similar to, but not the defrosting elements. Poor reception may due to corroded or dirty contacts caused by humidity and moisture. Search the internet to determine the location of those contacts which may be accessible behind a covering in the trunk.
