Good morning!

I'm purchasing this BMW and the amplifier got wet and there is corrosion at the connector. I haven't been able to get the amp out yet, but was curious if someone could tell based on this picture if it was DSP or non DSP HiFi amplifier. I checked the trunk and there seems to be just one big plug. However, I do see some other plugs that are not plugged into anything.
Anyone recognize these other small connectors?

I have seen some on eBay and was thinking about just buying one to see if I can get the radio working. They have an aftermarket warranty, but I'm not sure if BMW has access to any new amplifiers.

Any thoughts? Should I just purchase a used amp? Seems like a waste to go through insurance and pay a deductible.

Please see pictures.

Thank you in advance.
