My car is a 2018. Gunde is referring to a 2016. Correct me if I'm wrong but I thought the 2016 Astra had a different connector. Which is why it may not work. If I'm wrong and it is the same, depending on the radio unit, it may well work.
Thats correct. The unit I removed had one USB only. The replacement had 2x USB and Aux. The connection was a single Mini-USB on the bottom with a 5pin connector (although I believe only 2 pins had wire (but I couldn't see them)).
I have had my car taken apart in that area to retrofit the powerflex bar. Mine also had one mini USB and a SIL (SingleInLine) connector with 5 pins, mine had all wires for all 5 pins.
My guess is that the 5 pins then are :
12V
Ground
AUX-L
AUX-R
AUG-Ground
If your car was not equipped with AUX, then the 3 wires for that is probably missing.
This is a picture of the original one in my car right now. My car is a MY2016
Great thing if the 2 pins on the 5 pin connector is 12V is that this means that the 12V to 5V converter is onboard and then the 5V is probably stronger on the newer versions.
Also there MUST be some sort of usb-hub onboard, to enable the 2 USB's when there is only 1 mini-usb connector.
Were you able to pull the USB part out of the hole and replace it without removing a lot of stuff or will i have to remove the plastic centre part with the armrest to do this ? (Are the wires long enough to not have to take it apart. ?)
