Radar

Sorry, Ive never purchased a helmet that has comms pre-installed, Ive only used the Sena setup and have no complaints.
Good luck
 
Okay, short update. After a day of riding and using the radar setup I have found that running the app and charging the phone at the same time has overheated the iPhone. Now iPhone overheating is a known problem to apple but this is my first time experiencing the issue. All this means is I have to use the Sena Bluetooth transmitter instead of the iPhone.

Cheers
