Mp3player/reversing Camera 08 Invincible

[mudlux]

hi all

just got an 08 plate invincible hilux with the touchscreen satnav/cd model b9010 (aka tns700?)

i would like attach an mstation mp3 player which basically has 2 standard phono outputs

and possibly at a later stage a reversing camera

there seem to be loads of spare connections at the back of the unit but ive no idea what they are

any advice greatly appreciated

thanks
