I got an email this week from Pioneer stating that the new update disks were available, with a link to the Pioneer site. The CNDV-60mp disk doesn't show that it is compatible with the Z1, can I safely assume that it is?? I went to the TeleAtlas site and it appears that it is the same maps for all three Pioneer units.
Are these update disks good for only one unit only or can you use them on all your units? I also noticed that the Pioneer site called this the 2006 model year. Shouln't it be 2007 or have they just not updated there site?
This is my first time to update the maps - do they make many changes to warrent the cost or is it better to do them everyother year or so?
