I did a search and read alot... my problem seems a bit diffierent

Avic-Z2, with GEX-P10XMT.

No mods (execept parking sensor is grounded)

No traffic flow shows up on my map and also the button is greyed out.

XM radio works

Traffic events work

traffic events are displayed on the map

just no traffic flow.

I sent a new signal out via the XM website and also did a radio reset. Still not working.

Sadness

Is it turned on in the menu?

Are you sure you have the service from XM. I live in the Dallas area and it's not available. I thought I had the same problem but when I went to XM web site and looked under NAVTRAF and looked at the service area and found it wasn't available

Dawg6,

Which button is grayed out? Which screen? I have the same problem. I live in Jacksonville,Fl.

Go to xmnavtraffic.com You don't have the service in your area either. Check other city maps and you'll see that Jacksonville only has 2 of the 3 availavle features active. That's why your botton is grey.

You guys are correct... i am retarded.

When I saw that tere was navtraffic in my area i ASSumed that it menat both traffic flow and incidents. Turns out there is just incidents. That sucks ass.

Oh well on to the image and 2 wire bypass. If I cant get traffic flow, at least I can watch a movie or something.
