• Same as Legend HCx (+has barometric altimeter, electronic compass)

• Same as Legend HCx

• Same as Vista HCx (+has GLONAS support, 2 GB built in memory)
• Very quick satellite lock

• Megabytes of memory available for tracks; 10 000 points fit in a MB. Models with the smallest preloaded maps have even a GB of free memory.
• Expandable with SD card (up to 2 GB) for maps etc., but tracks are always saved in built-in memory

• No altitude information
• Log conversion to GPX requires a custom program by the name wnutrak

• Big space for tracklogs (938MB standard)
• Expandable with SD or SDHC card (probably up to 32 GB -- 8 GB is approved)

• Rather sparse placement of trackpoints, only "on changing occurrences", not every x seconds or x meters.
• Locks to roads on the map: not much use when mapping changing environments. It can be put in "off road" mode, but then it also does not do routing.

• Can not route through/via multiple points.

• Expandable with SD card

• No tracklog

• Expandable with SD card (up to 2 GB)
• Possible to record POIs:
  • Simply add a location to your favorites.
  • Then find the file /Garmin/gpx/current.gpx (in GPX format) and use it as needed.

• No GPS track logging feature for this device.

• Expandable with SD card (up to 2 GB)

• Expandable with SD or SDHC card (supports at least 8 GB - probably up to 32 GB)
• Hidden track log feature is already in GPX format.

• Wide screen;
• Multiple supplementary maps (put them in /Map directory);
• Capable of loading and searching at least up to 750,000 custom POIs — as are (all?) other Nüvis;
• Can route through/via multiple places.

• Touch screen needs a bit of a prod (but one gets used to this).
• Micro-B USB socket (this isn't really a bad point; it's just that these are less common);
• Routing through/via multiple places entails searching for each place, adding it to the favourites, and then selecting the desired favourites (it's a bit long-winded).

• In USB-storage mode compatible with all major platforms
• A lot of build-in memory (25 MB?)
• Expandable memory (microSD card - up to 8 GB)
• Waterproof?
• Profiles: Different settings for different actions, like mapping, biking, geocaching

• Price (around 220 € - June 2010).
• No Altimeter
• No Compass
• Same as Oregon 300??

• A lot of build-in memory (850 MB)
• Expandable memory (microSD card - up to 4 GB)
• Well-built unit, rugged.
• Waterproof
• Profiles: Different settings for different actions, like mapping, biking, geocaching

• Strange limitation (general to Garmin) in the way maps are handed: The device can only hold two maps at the time (gmapsupp.img). 2+ maps can be combined to one img-file. This was changed with the beta firmware, from the 2.99: the GPS load any img file in the garmin directory
• For some reason there is a 10.000 point track log limit.
• Screen OK but not as bright as e.g. Vista/Legend HCx.
• Price (around USD 400 - November 2009).
