On the Z1, is there a place where it shows my Sirius Satellite strength ? Poked around and could not find it.....

I don't think there is.

Look at this forum:

One of the gripes of the first poster was a lack of a signal strength meter.

out of curiosity, why is a singnal meter so important? is there anything that you can do to help the signal aside from mounting the antenna on the roof? with sirius either you have a signal - or you dont. i am just curious as to why people are looking for a signal meter.
