My stereo/CD is giving me problems that I can only assume are age related. The unit is 10 years old and its time to update anyway to one of the newer systems.My question. Is it really worth the extra $$ to buy a "marine" stereo at the Marine store? Or will a decent car audio system be OK? The unit is mounted inside my H376 at the nav station and is not exposed to direct weather. Plus the boat is in S. Cal, so the weather really never gets bad.Thanks. Bob.
