Unfortunately, the hope not fulfilled. The part (otherwise you can not call it) may have good hardware, but the software is a disgrace. ME she never left the beta stage and it is probably no longer do.
At the software is exposing that runs are sometimes not properly transmitted from the clock on the computer and these runs are then simply disappeared. Furthermore, the coupling between the clock and the Android smartphone is a joke. Constantly pairing is canceled, so that the clock needs to be completely re-connected. ATTENTION: The Android app is running anyway with only a few selected models and even there only with the so-called stock firmware (before acquisition necessarily inform!).. Custom-ROMs do not work and will it probably not. Whether it will ever be a compatible version for Android Lollipop 5.0, the support could not answer me, unfortunately. Due to the fact that Tom Tom has been facing a new watch-project (golfers GPS clock), I suspect that it will stay with Android 4.4.x.
Keyword support: There is a German-language forum where 2 presenters try to help. "Try" is that they give advice within their means. Intervene actively in the programs or even fixing bugs they can not. The standard tip is therefore: to perform a factory reset on the clock. After that all personal settings must be re-made. Runs, the result of errors, could not be applied to, then, of course, finally gone.
Why did I keep the part as long? Honestly, I know not exactly. On the one determined for convenience, because sometimes it was actually no problem, on the other hand in the hope that at some point but still a reasonable Software is brought out.
For me this is part of the bad buy of the year 2014. Tom Tom? For me never again. If I could, I would return the part.
