Actually, it's quite an undertaking for Sirius to do a channel update. They try to do them only a couple of times a year. It can be disruptive to the listeners as the radio locks up for a few minutes when the update takes place, some radios lose their presets, and some have issues if the update is not properly completed.
XM can (and does) do these kinds of changes on the fly in the background.
Channel mapping creates a lot of havoc for older tuners and they only like to do them when it is absolutely necessary. This is what happens when you have a system that doesn't allow for text changes on the fly. Clearly back in the early planning stages they didn't think much about this unlike XM.
Anyway... like most it is just one of those things you learn to live with or you can switch to an XM sub where this is never a problem.
wasn't it just recently where they moved channels around, like for example the area, the channel number changed and the name and that did not seem to be a problem adjusting, i think there were a few other channels moved around, also the 80's ,70's and so on changed names, so obviously its not a problem to do, they did not move to different channel numbers but sirius had no problem changing the names of the channels, so at least changing cinematic to the strobe should not be a problem. the website is not even updated, pure laziness, there is no excuse for that
Changing the channel names/logos/fancy background images is a small problem.
Honestly, I bet at least 75% of all Sirius radios could be kept on overnight during channel updates without a problem. Sure, you'd have to re-set some presets, but at least you wouldn't have to sit there while the thing reboots. And if you don't want to leave it on overnight, plug it in while you're taking that morning shower.
