You can pair with a speaker and it works, but anything with a mic no joy unless it is your phone. I still cannot see the benefit of answering my phone on my radio since if the radio is in range of my phone, I can just use the phone? It is dumb. Seems to me that they could make this a full-functioning TNC and corner the cheap market, at least on the ham side where you can do digital modes.
Agreed on Chirp, not only is it a much better application and interface, I've found that some of the settings won't stick if I use ODMaster (such as channel display and dual watch) but will if I use Chirp. Since all my radios except one (5RH Pro GPS) are compatible with Chirp, I have basically one file that I can use for all my ham radios and one for GMRS radios.
Honestly, this radio wasn't worth buying in my case as far as being a good addition to my collection, I have several others that work as well if not better that don't have the bugs and quirks this one does. It is small and light, I'll give it that, but that can be a con as well as a pro. At least if it does an Alice Cooper and goes under my wheels, I won't shed a tear. Then again, that fits for most of my radios as they were purchased with that possibility in mind .
