I have a 2010 non tech...

I have a cheap fold out headunit from Amazon. My plan is to only use this for Android auto and carplay.

If I take out the factory cd changer and place the single din hu there... Could you confirm if these steps would work...

Acc wire... Not sure which wire to tap, I could always just tap the wire connected to my dash cam by the fuse box. I assume there should be a some signal and 12v wires on the cd changer connector?

L and R channels, could I just tap the LR channel wires going into the cd changer? Then those taps would go into the LR out on the back of the HU?

If I can't tap the cd changer, I assume I can tap the AUX LR channel?

The ground goes to metal.

If I remember correctly, that should be all I need to get it going?

Thanks!
