This product (version 4.0) works with my V3 and V3x. It does NOT work with my new V3e.I am using the overpriced Version 4.0 disc purchased directly from Motorola.Software updates still do not recognized the V3e. Not sure which models listed work and which don't, but the fact that non-supported models seem to be listed is sufficient to be skeptical and go elsewhere. Yeah, and it's a penny, PLUS a lot in shipping!So, if the software works for you, it is pretty nice. If not, you're out. I gave a review of one star based on the fact that a model I KNOW doesn't work is in the supported list.
