Just bought one of these and fitted it in my car...i am blown away by the quality of this unit, which has:
4x50w amp, (22w continuous rms) is very powerful and has loud mode and volume normaliser
bluetooth (dongle included)
great phone control features (calls, phonebook, dialling etc)
wired mic with brackets and long cable
front and rear usb (with cabe) with full ipod control (new models too) and you can use either the headunit or ipod to control!
front aux in (3.5mm)
2 pre outs (one is sub / rear switchable)
3 stage EQ with pro freq adjust settings (ive never seen this before)
the display is large and clear and the UI is very easy to use
available online and for reserve and collect.
