I just purchased a navigation system and when it came i realized that it wasn't an MK4 but rather an MK2....

I did read a lot about it but could someone please clearly tell me the biggest advantages that I would have if I had an MK4 over the MK2...

This biggest differences and what I would be able to do with an MK4 that I wouldn't be able to do with an MK2....

Thanks
