Hi!

Apologies for the newbie post. Kindly close/delete this thread if this was already discussed.

I lost my Micro SD in my Chevy car that runs Polnav6_12_4. What I did was I copied the whole file from a friend that also owns the same system, but when I inserted them back in my car the system doesn't recognize it.

Any suggestion how to run a copy of Polnav from one car to different car that has similar system?

Thanks in advance. :)
