The phone in my 500E is called (per Motorola) their "Mobile TDMA Phone", no part number beyond that. And mine's been bench-tested and its dual mode nature confirmed. Neither Motorola nor MBZ knew anything about the phone at first, but I stayed on Motorola (I was trying to get an owner's manual so I could program its user features) until some service supervisor overheard what was going on and volunteered that he had a manual in his desk! Hw copied it and overnighted it to me.

One thing is for sure. and that is that the phone clips right in. 15 minute install for me, but I've had my console apart a bunch of times. The handset itself looks much like the old one, just is a bit more curved in profile. I'd be happy to send a picture of the handset if anyone would like...the trunk-mounted transceiver looks identical.
