I was just going to as a simular question. I currently have the XM antenna for my Z2 on the dash but the reception isn't that great so I was told that it should be mounted on the roof. Vehicle is a 2007 GMC Sierra (new body style). It has a single antenna on the driver's side of the roof. Can I tie into that instead of using the antenna included with the Z2? I'm going to look at that site too. As I type this I remembered that I didn't order navigation from the factory so I don't have a factory nav antenna up here. My reception for that tends to be pretty good (aside from it freezing once).

I did the by-pass to mine. The navigation's functions are available when the vehicle is in motion but the DVD's picture won't play. I also get the parking brake message at start-up. I'm going to try the one click of the parking brake thing to see if that does anything.

My nav froze last week. I was going to a casino in CT. Knew where I was going but wasn't paying attention to the exits. Just waiting for the nav to tell me to turn. I started to think that I had been driving for awhile. Then I realized that the nav froze about 40 miles earlier. Upgrade disk heading my way now.

Thank you very much for the info! I was reading the installation instructions again last night. It kind of sounded like that cable was for a different head unit but I guess it makes sense that it's require. That trim is a pain in the butt to take off (new body style GMC Sierra) but this should be the last time it comes off.

Having a simular problem with the XM Radio/Nav-Traffic connected to my Z2. Connections look to be good. Only things are aren't connected are the IP Bus In and IP Bus Out. Based on what I'm reading here, sounds like I need to connect one of them. My other vehicles usually either have XM or Sirius satelite radio. I know that has to be activated but there is usually at least one channel that works. Even if it's just telling you to sign up. Actually, I believe there are a few channels available before the subscription is done. When I goto source, the XM button isn't there. available to be used. It

Yes, I do have the GEX-P10XMT. Connections look to be good. Only things are aren't connected are the IP Bus In and IP Bus Out. My other vehicles usually either have XM or Sirius satelite radio. I know that has to be activated but there is usually at least one channel that works. Even if it's just telling you to sign up. Actually, I believe there are a few channels available before the subscription is done. When I goto source, the XM button isn't there. available to be used. It's there, but not highlighted like the FM or DVD for example. Tried resetting the unit but that didn't work. I'll pull

Finally got around to wrapping up my install last night. Went to activate/use the XM radio and found that the button isn't highlighted when I goto source. Everything is connected at the XM box. Aside from something coming unplugged from the Z2 when we fed all of the wires in, is there anything that I'm missing. Looking through the Z2, it's like the XM/Nav traffic doesn't exist. Thanks!

It's been a long Summer so my buddy and I finally got around to finishing the Z2 installed. Also took care of the 2 wire by-pass (works great!), satellite radio/NAV traffic and Vizualogic headrests with 9" monitors. Been trying to chase down the problem with it not booting up when the truck is first started. Sometime's it's fine and other times I can hear the relay clicking. shotgun_customs: We read your reply but aren't sure which wire to move that power wire to. Also have something new after he install today, there is a hum in the speakers for about 10 seconds after the truck

Subscribing to this. I've been wondering the same thing.

I downloaded the 30-something meg file last night and will burn it onto a CD and load it in my Z2. Then take care of the 2 wire bypass. Also need to install the satellite radio/nav traffic along with 9" Vizualogic headrest monitors/DVD players. Hope to finally have time to take care of that stuff next week!

Yup... that works! I guess I should read the manual some more. Navigation systems usually work when the vehicle is stopped or in park. I didn't think I had to set the parking brake to use this one. I'm going to be taking care of the bypass soon. Thank!

No, not warnings.

Last week I noticed that alot of my navigation features for my Z2 aren't working. The icons are there but they aren't bold to be used. The features that don't work are - Address Search, Go To, POI Search, Route Overview, Telphone Search and Cancel Route. Everything did work fine before. Any suggestions? Thank you!

So the bypass wiring is the same as doing the Z1? Just a matter of getting the upgrade disk or downloading from Pioneer's site if they put the "upgrade" on there this week, load that disk and then do the two wire upgrade and we're good to go? Sounds easy enough!

I'll check the power/ground connections. I've been trying to find some pattern but haven't been able to. One time I put my foot on the brake pedel and it powered it. Might have just been a coincidence through. The vehicle is the new body style ('07 ) GMC Sierra HD.
