Squint at a your tiny Garmin GPS if you want, but I won't...
'cause my SONY NV-U83T has an almost 5" screen. Works great.
Much better mapping than TOM TOM. GPS engine is fast, and
when satellites are temporarily hard to see, navigation continues
with a doppler/inertial-like, gyro-based technology that backs up the
GPS system- SONY's exclusive POSITION PLUS. Becomes my
handsfree phone via Bluetooth, interfaced flawlessly with my
cell phone. Don't listen to the Garminites, they just don't know
any better. The SONY NV-U83T is the cold nuts.
