HI all,

 

At the moment I own a Avic X1R Pioneer nav-set installed with CNDV-50MT. I recently downloaded the newest version of it namely CNDV-90MT ( only 3th disc ) which is Central Europe (which I supposed the only one I needed )

 

I burned the .ISO on a blank disc and therafter inserted into my nav/set. It did a reset and was upgrading nicely, but after the upgrade the nav/set display's "this is not the right disc". Do I have to donwload and insert the 1st and 2nd Disc of the CNDV -90MT as well to be able to use this version ?

 

Can it be that one of the disc is the main disc (probably the first disk), which should be always in the nav-set and the others ( 2nd and 3th disk) are only upgrade disk for the rest of Europe ?

 

Many thanks for the information given !
