In the Genesis, the DIS will display CD info (track names) if and only if the CD was encoded with this info utilizing the
CD-Text standard. It's really a shame that more discs don't have this info on them, as it's been around for almost 15 years and comes in very handy when using CD-Text compatible players such as the Genesis, but the reality of it is that most CDs (old or new) lack this extra info. After doing some research, I cannot figure out why not (as it's extremely inexpensive). I also cannot find a list of CD-Text albums, which would be interesting/helpful to glance at, I think.
As for newownerinorange's experience, I don't know why the IS250 would display CD info that the Genesis would not. It could be that Lexus added their own data info inventory for discs without CD-Text as a supplement, but that's pure speculation. I'm not aware of any devices being compatible with only some CD-Text discs - I'm pretty sure it's all or nothing. I'm stumped by that one.
Regarding newownerinorange's other comments... those issues have all been discussed here before. The Lexicon stereo system is far from perfect, but in the opinion of many Genesis owners (my generalization of the things I've read on this forum), its incredible audio fidelity more than makes up for most of the software errors/omissions that are present. It could have more functionality and the functions it does have could've been made to work more intuitively, that's for sure. This is the main (only?) area on the Genesis that appears to suffer from being rushed into production, or possible R&D budget overruns. There's a lot of positives, and at the core it is a very capable system, but a few minor tweaks would have gone a long way for those of us who utilize the stereo often (constantly!).
I do think we will see sizable improvements in the DIS' software for the Genesis' first big refresh. I like the simplicity of it, but think that adding at least a few more "advanced" features (even if you have to dig around to find them) is very important. Little things like improved "random" functionality, a folder list that stays put and remembers where you were while you try to navigate into and out of folders, etc, would make the experience much better. Hopefully that's coming in the near future.
