Bluetooth suggestion for a truck
 

I have an 05 Silverado 1500. An Iphone and i'm currently using a Motorola H500 but it is on the way out. I'm looking for a replacement and I'd like some ideas for good Bluetooth for a truck. I'm on the road all the time and I'm talking to clients so I need to beable to hear them clearly and for them to hear me clearly without the road noise.

Thanks in advance
