My HU-803 head unit has a knackered display screen only showing half the info and the rest is all yellow! Also the CD player jumps all the time so I have sourced a perfect second hand one.

The trouble is the geezer says it needs ‘RECODING’ ??

Never heard of this before on a Volvo radio, so whats the score if I just swap them out? There is no CODE as such it comes on straight away after disconnecting the battery so what CODE does he mean please?
