NAV question/bug/issue
 

I have an 01 so CD ROM Base, older version of software as I can do OBC/Radio display.... here is an issue i am having, the nav changes the map scale all on it's own from 1/4 mile to 1/2 mile.... is this an known issue as i could not find it via the search funcation...

strangly my 04 nav system on the m3 does the same thing but not as often...

thank you in advance for any assistance!
