Hello, i'm new and i've done some search before

I have a Clarion NZ502E since 2011 i guess and the original SD card with it died long ago.
It's the third one i've purchase but 80€ for a SD everytime is killing me.

Does anyone have the possibility to give a backup of the SD ?

With or without maps on into

I've try several magnet without success.

Best regards Eureka.
