Radio Not Working With Pioneer Head Unit

[Johnno420]

I’ve recently installed a pioneer head unit into my Vx sedan and Bluetooth works fine. When I try to switch to radio however the antenna doesn’t come up and the car can’t get a good signal. The volume also seems to be capped at 62 for some reason as well. Any help is much appreciated

Did you wire up the antenna trigger wire?

Did the antenna work on the old radio?

Antenna worked on the old radio until I disconnected the battery and set of the anti theft on the radio. Went to Holden to get the code but that didn’t work so I just bit the bullet and bought a head unit.

Where’s the trigger wire and could you send some form of video about it?

The blue wire is the trigger. Its also the switch wire for an amp.
