i have a pioneer 7700 mp3 deck for sale used it for about 1 yr and upgraded to a indash. The deck was a psp exchange a bestbuy also it has 2 years psp warrenty so if it fucks up bestbuy will replace the unit. deck was worth 399.99 when i exhanged it with my other deck that broke and was replaced with warrenty =)
i am asking 350obo i think its fair because it has 2 year warrenty with bestbuy so if it fails they replace it
