First, I would like to apologize for not using the BIG-5 to write.

For several days ago, I returned the garmin legand T because it is for left hand user and has the small display screen not easy for navigatingto drive.
I did my homework but don't know how to chose between the Garmin 76s and Magellan color or to wait for the new GPS 60.
Both Garmin 76s and Magellan color have almost the same funtion, but one is color. The Magellan color is easy to use and has extra memory card to store map data. However, I don't know whether it is upgradeable to Taiwan's Map or its quality is relaible. It is painful and I am tired of losing my way in US.
BTW, what are the differences between Patch antenna and quad helix attenna?
All thanks and cheers.
