A more general question - what's the max depth behind the dash for the radio?
Thanks

Vernon, just going from memory, but I think I would allow about 5" to 6" max clearance without modification of the Plus 2 heater box. Some one with their dash off may be able to confirm, but the measurement is a bit tricky to get as the heater box front is sloped where the radio hole is located. The heater box can be modified to extend clearance a bit, to say about 6.5" to 7.25". I found that even with heater box mods I saw on various archive threads I could not fit a "standard" modern head unit.
Even though the specified mounting depths of currently available head units may be ~7", this typically does not seem to allow for the plugs and wires on the back of the unit. The current DIN standard dimensions "sort of" fit the stock dash cutout for height and width with a little fettling and depending in the bezel configuration. I found the hole a bit large for ideal flit of the DIN mounting sleeve, but the bezel would sort of cover the gap. The DIN standard does not appear to have a mounting depth spec, although I would allow as much as 8" to allow for the plugs, etc., which is way too deep for the Plus 2 without the unit dramatically protruding from the dash.
If you are interested in an alternative, I think I posted some details on the US manufactured unit I eventually used earlier in this thread. The electronics are mounted in the boot, and only a very shallow controller is mounted in the dash, so no issues with clearance. If I knew I was using this unit, I would have had the replacement dash radio cutout made to suit. Same advise if you are selecting a shallow depth unit that uses DIN standard width & height; have the dash cut to DIN standard.
