smell it from the back , i know it sounds silly but if it smells of burning then i would not buy its also best to take the stereo out and put this one in before buying as you never really know with electrical goods best to buy brand new tbh
probably aload of crap they look like cheap tat that would probably break in days of fitting any one would be better of spending the extra money and buying individual quality parts from traders
put it this way , his basically not happy with the item he was a geneuine customer he payed up am i right and now his not happy you could still give him a refund because you did in all fairness advertise abit out with your title and description you did breifly say style etc etc so the situation...
it is abit over priced but im my opinion take it to a nice location with loads of light give it a really good clean and wax and you will have more interest then ever and decent quality pics also thoughs little touchs do help
