Hello, I recently replaced the OEM battery with the Duralast GOLD H6R battery and was able to start the car. However, my head unit is no longer responsive. I can access my rearview camera when I put the car into reverse gear, but otherwise the head unit does not turn on. I've initialized both the maintenance and factory reset to no avail.
Is this an error on my end or do I just need to reflash the car's software?
Thank you very much.
