How's the speaker volume on the Tomtom? I have a C220 (same model w/o TTS), and speaker just isn't loud enough for the car. The Magellan Roadmate 2200 has a much better speaker.
TT1-2 and TT1-3 has good volume.
To be fair, C220 is old and C230 does has good volume.
Magellan 32xx, 42xx series also has loud and sharp volume, except, there isn't any selection.
Nuvi 2xx has 4ohm speakers which produce loudest volume among all entry level gps.
(it also has many different voice selections like tomtom)
