Hello, I have a radio AVH-P2300DVD Pioneer, and I would like to know some information.

 

1 / I wonder if it was possible to update the software/firmware of the radio? (On the Pioneer website I find no information about it)

 

2 / If no update is available if it was possible to install a custom firmware (unofficial update)?

 

Thank you
