The Alpine CDE 133BT Radio unit is a great upgrade, Not only has it got loads of functions, Alpines build quality but its equiped wit hbuilt in Bluetooth, come with an external microphone too, Theres a DAB add on unit available, steering controls option, and a set of RCA (audio out for amplifiers) too, this is switchable from front to subwoofer, This unit even comes with a hard plastc carry case for the front when removed, this is a recomended radio upgrade..
