Right now I have Smart Map Pro DVD 1.3 and it's pretty much take me to wherever I program it on. Now that Alpine has came up with a new 2.0 and I wonder what is the differences between the two, more new streets? Well, the 1.3 I have now has no info on my neighbhorhoods and around town, only a few major roads are covered in the 1.3. Does the 2.0 would have more coverage? Is it worth $300 to upgrade?
