First off nice forum, lots of great inofrmation for complete beginners.
Having a bit of trouble........ heres the scoop
in a nut shell, just changed the HU(W-200 w/blackbird and dock) in my 2007 Tahoe, I wanted to keep my onstar/bose systems so i purchased an interface from peripheral. Unit works fine, but since the install (dec 20) every morning I must pull the audio fuse in the fuse block. It seems that the module freezes and will not allow power to the unit. After cycling with the fuse it returns to normal. I have replaced the module twice since the install and its getting a bit irritating. The shop that I had install the system said that "nobody" had a glich free harness for this yr model. They didnt carry the harness in stock so I purchased from another audio shop and had them install it.
UPDATE:
ran out and pulled the unit, on the interface the only decal on it has :GMAHLANB and below "general motors gm lan onstar interface factory radio replacement retention of Bose Amp and Onstar Option" A little red light that illuminated when i pushed the onstar button and a volume control for onstar.
I will call perripheral in the morning and double check. THe application guide shows that the 2006 and later models to be a different part number
UPDATE:
Couldnt get ahold of perephrial today but sent an e-mail last night about the problem. This morning the unit worked fine. Ran alot of errands turning the truck off and restarting. Around 4pm I made my last stop and killed the ign. pulled the keys out and opened the door. The head unit stayed on.......puzzled, i restarted the truck and turned the unit off and on with the power button, still nothing. I pulled the radio fuse from the block again and when i re-installed and powered up my onstar system went crazy, started dialing everyone in my phone book and such. SO i pulled it again and that seemed to clear it up. The owner of the audio shop told me this is the down-fall of buying the first gen of interfaces....they will always have bugs. Why even release them or much less sell them if they are this much trouble?
Ive also noticed that the "brake dance" to view videos seem to not work when it has its fits. I have to do the fuse pull to let the system accept the brake sequence to view anything. Sometimes it works sometimes it doesnt.
Anyone else ever have this much trouble?

NO but i sure will look it up. When I had purchased the equipment, they told em that this was the only cmpany with harness that was "bug Free" so i jumped on it...150.00 later it has caused more trouble than anything.

kinda, what the other guy said is true, you need a better adapter, the peripheral piece is more multi-purpose and doesn't work so well in the more difficult apps. Try Metra's GMOS-LAN-02, I have personally istalled them in your exact vehicle and have never had not one single problem. If you don't have a local dealer of Metra then just ebay it.

I just got off the phone with Peripheral, they said they havent had any problems or complaints. They said they would ahve an engineer call me about the situation.
NOw I am pretty much stuck with a 150.00 POS, unless there are chances that they will refund my money.

onebadtahoe, Any updates on your situation? I just installed a avic z1 in a 2007 Denali and used the PAC OS-3Bose harness. It looks to be the same as your GMAHLANB. I am having the same issues... It appears the accessory wire is not being powered all the time. This is what is causing the issue. You can hear the relay cycling multiple times when it happens.

just run a new ignition/accy wire from the bottom of the fuse panel with a female quick disconnect up to the radio. they are extra male prongs that supply good power.
