Hi,I guess this will be a basic question for a lot of you but as I
haven't wired one in before I thought I would ask your advice. On the
power connection to the unit (radio/cassette (reasonably new)) there
are two different supplies, one is 'switched' and one 'continuous'.
what is the difference between the two and do I have to use one or the
other or both?

Continuous (permanent) is usually the main power feed to the unit, and
gives the supply to the amplifier, and also keeps the station presets,
disc position, etc stored when the unit's switched off.

Switched (accessory) tells the unit when the vehicle ignition's
switched on, allowing the unit to switch on and off with the ignition.
This is usually a relatively low current feed.

In virtually all cases, you need to connect both to get the unit to
work.
