Just got this phone after being bored with an iPhone 5 and When attempting to connect my phone with a USB connection in my car I get a connection error on the display of my radio but the phone appears to charge (albeit extremely slow) and the USB icon is displayed. The phone also keeps bouncing between installer and media mode when plugged in, neither of which work. I've tried the OEM cable as well as a logitech one I have for another device with the same result. Additionally, while I can pair my phone with my vehicle via bluetooth, it will only (slowly) download 12 of my 350 contacts. I noticed too, when I am listening to the Radio/XM and using google maps, the phone will not interrupt my radio with voice directions via bluetooth like my iphone did (which I really liked). Has anyone encountered similar problems and i so, how did you resolve them? Any assistance would be greatly appreciated. Thanks in advance!
