The programming cable is CT-155, unique to the VXD-720, and cost about $50. The XPR cable will not
work. The external speaker/microphone is MH-66 A7A, which fortunately is interchangeable with a few other Vertex radios, so it should be easier to find. Again, an XPR speaker mic will not attach to the VXD-720.
I don't have an XPR series Motorola HT to compare with my VXD-720. From what I can tell looking at pictures of the side accessory connectors, the Motorola XPR has a tab at the top and a locking screw at the bottom of the connector. My Vertex has two screws, no tab. Therefore it appears that the programming cable, and any other accessories such as microphones, are not interchangeable between the VXD and the XPR, which has me baffled. Typically Motorola is pretty good about using standard accessory connectors.
The batteries appear to be identical though, which is good, as I hope to find some Impres batteries and charger at the Dayton Hamvention. The Vertex supplied battery is only 1300 mAh and barely gets through the day.
The antenna uses a standard SMA jack, so the XPR antenna and VXD antennas are interchangeable, as are many past Motorola series HT antennas.
