Looking to add a new headunit to your Sonic?
Here's what you'll need:
- Metra 99-3012G Dash Kit
- Metra 40-EU55 Antenna Adapter
- A new headunit, single or double din. The dash kit comes with a pocket, if you choose to get a single din radio
If you have the Connectivity Package and want to keep your USB and Aux inputs in your "top" glove box, here's what you need:
For USB
There will be a male Mini USB plug that plugs into the stock radio.
You will need:
- A new headunit with a REAR USB port
- This adapter
Simply plug the Mini USB into that, and then that into the new headunit, and you have retained your glove box USB port.
For AUX
The dash kit comes prewire with the RCA's to keep that, so if your radio has a REAR auxiliary in (using RCA) just plug it up and it works)
If your new radio has a 3.5mm AUX in on the rear, you will need one of these adapters.
If you want to keep the Factory settings controlled by the stock headuni (including DIC language, Bluetooth, etc) here's what you need:
- This module
There is a plug that looks similar to an S-Video plug, on the side of the module included in the dash kit. You just plug it in there and go, from what I understand.
Here's what a Double Din will look like in the dash:
And here's a Single Din:
