I'm not sure if anyone is out there,but I've been trying for a few months to decide between the droid charge and droid x?? I'm wanting to use this with my bike (motorcycle) and I'm wanting an app that is name announce caller id that will go through my sena smh10?? Now, I've read where, my zumo 550 and the smh10, is only compatible with the droid x but I don't thing I can do the same things with the dc than with the dx!! Does anyone have ANY suggestions??? Thank you for your timely response and have a very very blessed day!!
