Phillipbj, do you have a bluetooth helmet or do you use something to get bluetooth in your helmet. I use my iphone when riding and have a GPS app that I really like and I too am able to make calls, answer calls, listen to tunes and still get voice directions from the GPS, but I have earbuds running from my helmet to my iphone. Wondering if there are some inexpensive alternatives.
I have a Nolan N103 helmet and the Nolan ncom Bluetooth kit. It fits into a dedicated recess in the helmet perfectly. It paired with my iPhone, no problem.
Expense is subjective, but I have about $550 in mine, which is dang expensive to me. But it has worked great so far.
One thing, I do not use my phone for tunes. I have an iPod connected by cable to my helmet. It is a iPod shuffle and I clip it onto my shirt or put it into my pocket. Music stops when I get a call. I hope the same thing happens when I get voice from the Navigon app. I haven’t checked that yet. Been raining in south GA.. Yea!
