Has anyone tried this Zerin DVD update with any success? Its on sale for $150 for the 05 G navi.

 

I havent yet but $150 sounds tempting to buy since the normal price is $190. I have 6.5 right now, but for me the roads around here havent changed much where I have only seen one place not show up on the map. All the update has is just more POI's and map data. The navigation software should be basically the same. May be worth it to buy if your area has changed alot recently.
