I have a single din unit Sony m600r.

It has rca input for autochangers.

This might be an option to you.

I used the headphone jack to connect using jack to rca lead from Dixons

(about

£12).

Because the input on the unit was for changers only, the Sony would only select aux when a changer is connected so I had to buy an Autoleads lead that fools the headunit into thinking the aux rca input is a changer.

That was

£40.

The Denison is something I looked at but is

£100 and the only advantage is that you can control the I-pod through the head unit

(quite a big advantage I know, but has big compatibility problems I have heard.

)

Not sure if the above is clear to read.

.sorry

but it does work well, and quality is very good from my mini ipod
