Under Maintenance information on the NAV screen is it possible to store any maintenance that has been done during the ownership of the TCH?

I have tried inputting information on the body side molding I had installed last week and when I try to add the date it was installed the NAV brings up a message that says the "date has past".

I had hoped to store all my maintenance in the TCH NAV but maybe it's a reminder screen for future maintenance only. Or are there other benefits to the maintenance information screen?

 

I got the same message when I tried to add previous information. I gave up after that and figured it would be easier to write it in a small notebook.

 

Not sure if this will do it, but you can try. (Don't have the chronological steps memorized, so I'll just wing it):As I said, I don't know if the preceding junk will work, just a try.

You will definitely want to keep a hard copy because if they need to change out your NAV/CD/Radio head, they cannot download what is stored. (I had to have mine changed out three times due to problems with CD changer. Lost all stored data. )
