Does this "over-laying" happen to anyone else ?

 

It only happens occasionally but i'd like to fix it if i can

 

Not had this and cannot find anything definitive in the manual but is it trying to tell you that 2 or more signs are in force? When this happens have you looked on the main maps display to see how many signs are being displayed there.

 

From the manual the Maxi-dot can only display one sign but the map shows all that are in force, maybe that is just the maxi-dot saying there is another sign (no overtaking etc) but the speed is the most important

 

Just a guess

Flybynite is correct. That means there are more signs to display.

If you select the sign-thingy instead if speed on the maxidot, all sign (up to 3?) will be shown.

Cool guys , thanks

Also, it should show multiple signs on the MIB unit. as long as you have the speed limit sign on the LHS of the screen (ie you have closed the additional box thingy)
