There are elegant solutions available to implement remote PTT for radios such as Motorola's XTS5000. This involves a blue tooth accessory attachment to the XTS5000 that comes paired with a PTT switch one can attach to the steering wheel. I went with a wired PTT solution from a tactical radio equipment supplier. If you decide to go that route, look for a supplier that offers "strength hardened" wires. My reasoning for choosing a wired PTT is: 1) eliminates BT drop outs, and 2) fewer battery issues to manage. Oh, and I sewed a button onto my safety vest for attaching the PTT switch whereby I could operate it, in a pinch, "hands free." N7RV
