Garmin to use MediaTek GPS chipset
No, not for all their devices. They’re smarter than to rely on only one supplier for their GPS chipsets. But apparently Garmin is going to use and have been doing so for a while - the new all-in-one MediaTek MT3329 GPS chipset on their GPSMAP 60 series

MediaTek MT3329 is very sensitive at -165dBm and consumes very little power as well as boasting rapid time-to-first-fix (TTFF). Also listed as a feature is the ability to provide positioning even under slow movements like hiking or mountain climbing.
