The car is an 05 Mk II Octavia

The unit going in is an Alpine CDE-173BT

 

I'm confused a bit about the swap.

I know i needs a facia adapter for a single din and was going to order this 1

And this adapter http://www.caraudiodirect.co.uk/install-adaptors/skoda/octavia/ct20sk01-harness-adapter-for-skoda-octavia

 

but there's 3 aerial conectors

I also read that i will have to run a switched power supply from the fuse box to the radio/aerial ?

 

Heres the conectors im working with [Thumbnails] and i know i'll lose the CD changer

               

Well, it rather depends on the aerial connector on the new head-unit. It will be either 2 or 3 on your list.

Running a switched live it not a problem, just test one of the empty fusebays in the fusebox and use a piggyback or spade connector and in-line fuse. The underside of the steering shroud is held on with 5 or 6 screws.

You'll need to do this anyway for the new head-unit as there is no switched live in the quadlock (OE units are controlled by CANBus commands).

Thanks

Ok i piked everything up today and did a test fit.

 

On the ISO adapter should i leave red to red and yellow to yellow ?

can i conect the aerial to the blue power ant comeing from the headunit ? Or run a switched power from the aerial to fusebox

The switched power to the headunit from the fusebox what do i conect it to on the ISO
