Which one is better in your opinion?? any why.
Thanks for your help.
The 520 is a newer unit. It uses an external GPS antenna which is preferable to the internal GPS of the 334. An external is more accurate, and less prone to interference. The parts and components of the 520 are a little easier to obtain as well so I would go with the 520.
