It is because the +12v connection for the ignition switch then becomes live. So turning on the radio. Putting an inline switch which you can turn off separately will solve that. Refer to page 27 of the user guide here:

https://www.manualslib.com/j/jvc'x31mbs.html

The red wire is the switched supply and the yellow wire is always live to retain the memory.

Hope that helps.
