I have a Kenwood auto radio DPX530 and no operating instructions

Not the same model but might work?

Kenwood TK 3200U2P Protalk UHF Radio Instruction Manual All Reset Mode

you need a double size DIN , this is the size of the radio location , an ordinary radio is just DIN , so space needs to be twice the size of radio , there is usually a wiring adaptor available so that connection of aftermarket devices is made easy , any good auto spares shop should have these , then just remove the unit in care and follow the instructions with the kenwood

Try WWW.MODS.DK They have manuals for all sorts of radio's. You don't have to register if you only want one or two downloads from them.

Here's the manual:

and some other info:

Here's the link to their manual lookup, although I don't see DPX530 on the list DPX503 maybe? http://www.kenwoodusa.com/Support/Car_Entertainment_Owners_Manuals/
