Is there a Navigation Theft code?

When I go to Acura.com to sign up for the owners link, it asks for the Radio code and I have that on a card from the dealer but then it has a space for the nav. code? Is there a nav code, On my radio card I tried the numbers below the radio code but it's to long to be the nav. code.

 

In other Acuras its a four digit code. Not sure if thats changed or not.

 

No Navi code anymore. Probably because the Navi and head unit share the HD and are now one and the same.

 

Try putting in the radio code twice. I think that is what I did back in October - I think.

 

I called the delivery guy at the dealer and asked this question and he said that older units had two separate codes but in the 2009 TL it's the same as the radio code.

 

It may be the first 4 digits of the Radio Code.
