I bought the TomTom Runner 3 + headphones model, I was under the impression it had a heartrate monitor but it doesn't. This is OK however it seems some functions on the watch don't work without one? Can I buy a separate HR chest strap or such like? Any Google search seems to throw up the Runner 3 HR model. Thanks

    You can get any BT+ compatible strap, but don't necessarily go for the priciest ones. Most BT LE devices should work, but some work better than others. Price seems to not be a factor as the cheaper ones often seem to work better than the expensive ones. This is due to the fact that cheap models are more likely to use the base BT protocols and not customize them for advanced features or settings like more expensive models do (and there is no way of knowing if a manufacturer has tweaked the protocols to take them out of compliance). The BT standard is in such a way a 'standard' that it can be widely interpreted with different settings for buffer sizes, time outs, profiles, protocols, antenna configurations, etc.. TomTom cannot change their code every time a manufacturers messes with the BT coding. This is a case where paying more will not increase the chances of connectivity, it may actually decrease it. There are thousands of models out there so there is no way for TT to test them all and since the manufacturers often tweak the BT settings there is no way to know upfront if a device will work or not.

    Even with a strap you are not going to get Fitness Points, HR tracking or any other features, like that, as they all require a built-in HR. All an external strap will get you is HR during sports activities.

    I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.

    Sorry if I sound a bit clueless, does that mean the other functions are pretty much useless on the watch, with or without a HR monitor connected, then? (gym, indoor cycling, freestyle etc.) They continually search for a HR but are never going to find one. Thanks.

    You should have HR turned off under Settings>Sensors>Heart if you have a non-Cardio model and are not using an external strap. It will still track your activities and in run and cycle modes will estimate calories based on METs data (based on pace). Gym and freestyle will still track activities but you will get no calorie data as it has no HR. Fitness Points require an HR watch by design, so you will not get this function (which is of limited validity anyway).

    That's brilliant, I had HR turned on so that was my problem. Thanks so much. Natt
