I need a running gps watch/gadget with MP3 playback?

Any recommendations on a watch or mp3 player that has gps? I used to run with my iphone so I could track my run and listen to music, but now I got the note 3 and it would just be absurd to run with such a large device (but it is great for nearly everything else). Price isn''t a big deal as long as it is quality, but I don't want to carry multiple devices (i.e.watch and mp3 player). I've seen the motoactv but apparently its discontinued and I don't want a device that's going to lose support anytime soon.

Need?

I would argue against an all in one device. If you had earphones in, then the lead would have to stretch from your ear to the wrist at its full extent, when the arm is close to the body the lead would hang low and this is the problem, the lead is likley to get caught in every bush that you run past ripping the earpieces from your ears. Not good for a consistant run if you stop every 100m to put the ear back in again. With the iphone you wore it in a pocket or on your arm and the headphone lead was pretty stationary and didn't get caught so you wouldn't have had that problem

My advice would be a cheaper GPS watch that has the functions that you want plus a small light weight mp3 player, you can get cheap ones to use just for running from many big supermarkets and stores (quality of playback isn't important when you run nor is the ability to hold a million tracks)

As for the Motoactv, this was a short lived watch, however if you want it then they ill support it for a couple of years still
