Trusted Reviews tests the Garmin StreetPilot c320 GPS Navigation System which seems to share quite a few ideas with the TomTom Go.
Quote from the review:
“The StreetPilot c320 bears an uncanny resemblance to the Tom Tom Go, although it is a bit more svelte. The SD card slot is located on the left hand side, rather than at the front on the Tom Tom, and on the right you’ll find the power button, mini USB connector and an analogue volume wheel. The latter is a great feature, making it very simple to adjust the volume as your environment changes, or as the music on your car stereo gets louder.”
