...sirius/G.P.S./bluetooth=$$$ is a concern.? I have a sirius radio & veh. kit. Car comes with am/fm/ cassette. ( no aux plug ) Sirius through new stereo would be nice but would have to buy $120.00 worth of extra parts. Plus new stereo.Got an offer to get a stereo must be my folks catalog they have a coupon. ( it was nice of them ) This catalog has J.V.C.& Boss. One has aux plug & u.s.b. port. One has h.d. radio & aux plug. h.d. radio seems nice but don't need that & sirius. Have lighter in car but want that for g.p.s. when I get it. Maybe either bluetooth in g.p.s. or a visor bluetooth. Need lighter for sirius & g.p.s. Can use cassette with sirius or fm modulator on radio for sirius. But would have to have sirius seperate not in radio. THOUGHTS. Thank You.
