I received an upgrade notification today. Will my original settings be changed after the upgrade?

I just went to the 4S shop today, and I can't upgrade the car system. The original 360 camera is not clear and can't be calibrated. Regarding the transmission defect issue, the after-sales service at the 4S shop will apply to the manufacturer and get back to me. Also, I'm wondering if just changing the DSP will improve the original audio system since I don't like it. I'm considering the Pioneer 500A, which can connect directly with the original plug without installing separate loudspeaker wires.

Are there any Vellfire owners with spare original rims or looking to change rims? I'm interested in buying a set of original 17-inch ones.

Do I need to activate the system again after upgrading to the new system?
