2016 BRZ. Just did install myself. Crutchfield sent everything and all is well except hd radio reception is horrible. The stock was fine. Now it’s barely there.

1. Antenna is connected. The blue wire from metra has power.
2. Although there was no connection for the stock ground I cut the wire and grounded it to the HU.
3. There was no connection for the gps so I did not connect it.

Am I missing something?

Thanks
