Memory Map Adventurer 3500 GPS unit review

The Adventurer 3500 is a large, touchscreen, general navigation device. It’s bigger and heavier than most bike-specific options, and fixes via a plastic mount (Garmin 705-style) that attaches with zip-ties. Its size, user interface and lack of cycling-specific functionality don’t make it an ideal match for riders.

Operation is entirely touchscreen, with only a single power button. The quality of the mapping on the large screen is excellent, with high resolution displays of 1:50,000 Ordnance Survey maps for the whole of the UK. However, the interface isn’t really designed to be operated while riding, or with gloves on, relying on quite small on-screen buttons and menus.

Because of this, the device comes with a small stylus on a lanyard to make precise picks more easy – though this hardly makes it more usable mid-ride! There’s no facility to display any particularly cycling-specific data on screen, other than current speed and direction, and there’s no support for external ANT+ sensors.
