I would have to stand by Calvin on the visuals remark - I have a Mark II and have no visuals on my tuner as well. But, as mentioned above, I am running v1.03 and not v2.0b so that is probably what is going on.
I have tried to install the new software version but am having a problem getting it to even try to install.. I have reported my problem in the bug reports section of this BBS and look forward to getting it fixed.
In the meantime, no visuals for my tuner
I would also like to note that I spent some time yesterday searching each frequency in my area (Dallas Texas) for any station broadcasting in RDS - many web lists report that there are stations here that do but I did not find a single one, at least not yesterday. It was raining, maybe that was it..
