Delco Electronics CDR 500

I have this headunit from an Astra G to decode. I know that the code on this headunit is stored on a TMS370 chip, I have taken the headunit apart and can't find a chip with that written on top of it.

Could anyone tell me where the chip is/what markings should be on the chip?

Thank you.

the chip is under the small plate metal.
here is a solution to read the 370 tms
