by against TomTom highlights features like running against a pre-calibrated ghost or a custom path. This feature is nice but is not yet available (supposedly in short a future update).
I cardio coupled with a Bluetooth sensor, immediate coupling and proper operation. still a regret, it is not possible to display heart rate outside of a running session.
finally, as I use the watch every 2 days and I transfer to PC, the gpsfix are responsible regularly and the fix is quick at each departure (under 30s)
