“A program cannot be read, please consult to a dealer”

[JayM]

Hey everyone, 

I have a 2005 Toyota Crown and I’m having issues with the Nav System. I have recently jump started my car and I have had had a message come up saying “A program cannot be read, please consult to a dealer” 
I can’t use anything that is run through the Nav System e.g A/C, Music/Audio, System Setting etc.

Prior to being jumpstarted it was working fine, just curious as to what the problem could possibly be and how to go about fixing it. 

I have seen a few forums about Lexus’ having this issue but nothing about a Crown having this issue. Just wondering if anyone could point me in the right direction 

Thanks
