UPDATE: Check out our MediaTek vs. SiRFstar III smackdown.
Two independent reports are confirming that the new Garmin eTrex H series is using a MediaTek chipset.
One is coming from Groundspeak, Geocaching.com’s message board, where people are reporting good reception.
Another report, via GpsPasSion, includes screen shots comparing the MediaTek chipset in the Vista HCx with the SiRFstar III chipset in the 60CSx. While I can’t read German, it looks like the Mediatek chipset holds its own pretty well in that comparison.
