Sony CDX-F7705X Car CD / MP3 Player

i bought this product from a friend for a hundred and fifty dollars. it is an excellent deck, i love all the features such as high and low pass filters and sub volume control. it has superb sound quality and despite what others think i have no problems with all the functions and controls. after about 6 months of head banging seat thumping use, the display began to on and off by it self. then eventually stopped working all together. i cant see any of the functions to know what i am doing. frustrated i reset the deck and out of memory and a good ear i reset my settings and now don't change them because i cant be sure what i am changing. i have heard of this happening to this deck before. i still love the sound quality of this deck and would recommend it to anyone . in fact i am currently looking for another one.
