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.

Update... Got everything installed in my Denali and IS working fine. I also wired a SWI-PS to retain steering controls. Until I programmed the unit for version 2 the ignition wire was acting really weird. After programming to version 2 all is well! I can't get the SWI-PS to program but thats a different story.

sorry i havent caught you guys up....its been a hella week. Im still have some issues. As long as I leave the ign. turned off for an hr or so It seems to work fine, anything shorter than that I cant cycle to view video. I still havent heard back from pac and have called 3 more times. Stopped by the audio shop and they finally told me im on my own, even though they are a pac dealer I didnt purchase the unit from them therefore they wont help unless I buy a new unit from them. When i was talking to the shop they did say they had to ground out the module to make it work................he said that the current was fluxuating and thatw as the only way to get it to work. I also asked them about the all in one trigger https://peripheralelectronics.com/prodDetail.asp?strProductid=675&strSearch= to do away with the brake cycle thing and they looked at me like i was making something up. I am also goign to do a product review on this unit.....i am very disapointed in the blackbird performance.....maybe the module is the problem, but it really sucks having to wait 15 mins for the damn thing t power up. to be continued.....

UPDATE:
Went to the audio shop that I purchased the interface from and asked them to fix the damn thing. They pulled the unit out and called me to the back. They wanted to show me the mess that was behind the dash, half *** taped....a 10 yr old could have done a better job. I had broekn tabs and clips for my a/c controls and dash trim. They got on the phone with tech support to make sure everything was going correct. PAC said that they have worked out all problems and it has to be the wiring. The tech started double checking everything to find wires mis-connected and a big mess. I had them install the all in one trigger and everything is working great. Its amazing how a few wires can make a world a difference. They said they have gotten quite a few "repairs" from this shop and can't understand why they are still in business.
I give major props to the guys at Vision Audio( lubbock, san angelo, and midland TX) for the prompt service and the kindness of fixing someone elses screw ups.
As for anyone else in the west texas area stay away from Bladwin Electronics in Odessa.....you may get a great price, but will pay for it in the long run. These guys had my vehicle for almost 3 days for the install ........don't you think they had ample time to get it right?
Thanks to all you guys for the help
