Ok, so I rang up the shop, who were going to fit my mp3 autochanger,
and 4 new speakers (all paid for up front despite the fact the fitting
is next Saturday), and said "I've changed my mind, I'm going to
replace my head unit with a CDX-MP40, and forget the autochanger".

So, since the MP40 is £35 quid cheaper than the autochanger at this
particular establishment, I figured they'd owe me £35, plus maybe a
bit more because I imagined fitting an autochanger (in the boot, or
under a chair) requires more wiring work and some kind of frame to
hold it in. Whereas a head unit just slots in, and the wiring's
already there for you.

Oh no, they said, it'll cost the same, because it costs more to fit a
head unit. In fact, remarkably, it will cost exactly the same amount
overall to fit the 4 speakers and a new head unit, as it would have
done to fit 4 speakers and an autochanger to my existing head unit.

Ok, maybe some of you guys can help me out here - doesn't sound right
to me that I should be paying £35 more to have a new head unit fitted,
ie it's £35 cheaper if I have an autochanger fitted and wired up to my
existing head unit.

They've already got my money, as I paid up front. Now I'm starting to
feel a little like they're ripping me off...

thoughts?

cheers,

Matthew
