Among other rattles, noises, vibrations, ect. , i think the very cold snap we have been in lately, 1-15 degrees, have temporarily made my CD player inoperable. I noticed the other day that very small bumps and potholes, which normally would not ever affect the sound quality, caused several second delays in the music. Today on the way to work, about 10 degrees or so, - it did not work at all, and in fact, gave me an "error" message on the display. Wondering if any one else has seen this in their trucks also. I also have many noticeable vibrations, clunks and rattles that were never there until we got into the freezer several weeks ago. Any ideas?
