Brighthand says about Garmin iQue 3000 GPS PDA:
Curiously, unlike almost all other devices on the market, the iQue 3000 doesn't have a proper 5-way directional pad. Instead, it has a simple up/down rocker button, akin to the buttons on the old style Sony devices, or Palm models before they adopted one-handed navigation.

Instead of having a latch that releases the GPS antenna, as on previous units from this company, the 3000 simply has a recess where you can stick your finger in any pry up the antenna. Deploying the antenna still automatically launches the GPS software
