Yaesu makes one radio with Bluetooth built in. I suspect others will follow shortly.
It is possible to adapt a BTA II from Cardo to work with just about any headset. The Motorola one works best, however. If you want a schematic, e-mail me. As it is, it will NOT work with an Icom (not enough drive). The last two Cardo units I bought cost me $10 each. They are no longer made.
Pacific Plantronics makes an adapter too, but it has to be adapted to a nominal 13.8 vdc supply, and doing so is a lot harder than a first impression would otherwise indicate. It is also VERY costly.
There is one made in Europe, and here is one reseller: (http://www.wsplc.com/
). There is not currently a distributor in the US, but rumor has it that a deal has been signed, but I don't wish to share that at the moment. The problem with it is its cost. Delivered from the above British retailer to the US, brings the cost to almost $300 US. This DOES NOT include any adapter cable necessary, nor any headset. They too recommend the Motorola.
One of the reasons the Mot headset is recommended, is because it is noise canceling, and the mic itself is placed directly in front of the mouth where it should be for mobile work.
