Hello all. I'm hoping someone can explain the difference between DVD based nav systems (like the nissan OEM) and non-DVD based ones (like magellan).
I pretty much understand the drawbacks of DVD based (expensive to update proprietary discs..etc). do the non-dvd ones automatically update the maps via satellite or something? I noticed one of the aftermarket websites said "flash memory storage for maps". So where do you get the map data to put on these flash cards?
I saw a portable magellen at sharper image the other day. looked nice, but was around $1500. I'm thinking we'll be picking up a portable unit within a year or so... We didn't want all the pkg options, so getting OEm nav would have been a $7K upgrade for us...
Thanks.
