Modding Avic-N1/N2 Nav DVD’s

POIDT001.IDX----POIDT028.IDX  are used for street address indexes

POIDT029.IDX---POIDT042.IDX are freeway indexes

POIDT043 are your point of interest files.

I see now the diference between the formats of the old and new dvd's.  The new version will be much faster due to the way the index files are made. The index files have their records more compact as they have much space removed when compared to the old version.  You can see the difference by comparing the old and new "INDEXDAT.KWI" files.

I did waste a DL dvd.  The nav would work, but I had to be within 5 miles of intended destination for it to map properly.  I copied the IDX folder carrying all the nav guidance indexes from the 50 series disc to the 40 series ver1.2 and will see when I go to work today if that works.

Gotta pay for them.  If you are going to do that, you may as well buy the CNDV60 so you have the most recent

Of course it will work in your avic, Pioneer makes everything backwards compatible.  It will not turn your old avic into an n3 though.  It will give the N1 and N2 the same mapping and navigation improvements as the N3 has.

As far as the 50mt disks turning your n1 to an n2, that is true with the exception you won't be able to watch video while moving or use most of the navigation functions while in motion (unless you have the voice recognition.)
