W211 Android Radio does not turn on
2005 E320CDI....was without battery for several months due to an engine problem, but before issues started, radio was running fine, now it wont turn on
I have an android radio I installed several years ago...exact same install steps as here:

After getting the car back from the Mechanic who fixed the engine, radio does not turn on. I have checked all the fuses, engine bay, driver side, and trunk, and all are good. I am getting power to the unit.,...but not sure if its correct voltage etc. I have also bought another head unit to ensure it the radio itself ( btw, both head units fuses are fine)
Here is what I have voltage wise going to the radio
