Sorry for the delay in reply
No, hopefully you have bought another dud.
The reason it didn't power up straight away is there is no earth output on the CD changer port on the back of Alana HU.
It has to be done through an additional Illumination cable for us
Ibiza owners I'm afraid. This cable is about £10-£15 from a VW garage.
It took me ages to work out why I couldn't have an in dash changer to start with. I then borrowed a mates illumination lead from his Polo to test it with that, it has a separate earth and the unit suddenly powered up.
However if you can't wait and you are reasonably competent at wiring things up, check the '
How to guide' out i have put on my website to
help. Link below.
If you just want to test the unit it first though, before spending money or time on it.
Use some wire like speaker cable to link the metal screw threads under the rubber dash stops on the unit (check the link for a pic of what I mean) and the unit will power up when it all connected up.
