Hi Line AV Input

[Keith]

Yep correct

You can get a set of leads from the "adaptershop" on ebay for around £15.
Remember I think AV in is NTSC (not Pal) same as the reversing camera input so check your source is switchable
Also audio is only mono

You will need £400 worth of BM54 Radio and Leads for Stereo or a slightly messier way you can stick the AV into the reversing camera input set up a switch to toggle it on and off and use the tape input for audio.
