Hi all, recently purchased a 03 Boxster S and on 350 mile journey home in 80 degree + temp with top down the stock premium Bose stereo went into "protect mode" and CD nor radio would work. After about 1 hr stop in shade worked fine. No problem since till yesterday when same thin happened in lower temps but after about 1 1/2 hr driving. Anyone experience similar problem, should I have dealer check it out??
