Has anyone successfully installed a pioneer avic d3 HU in their camry 07?

I have a Camry 07 Se with non navigation premium JBL system.

So far i have swapped out the rear and front speaker with infiniti 6x9 and before the pioneer deck i had a alpine tilting head unit, I forgot the model number. I also bought the scoche amp adapter for 90.00 at the time because Best buy said that I would need that in order to play/hear music.
So when I got the pioneer avic D3 I had trouble getting it to power up. I blew a few fuses along the way and saw that the light on the scoche amp adabter wasn't blinking at all (it would blink with the alpine head unit) so I took it to best buy and they said they had the integrated harness for the JBL system by metra *it ran around $18.00* and it looks similar to the Metra TYTO-01 JBL Amplifier Interface Harness but it didn't cost me 80.00.
So everythign powered on after best buy took a look at it but now the only problem is I get no sound what so ever... Not even a buzz. Has anyone come across this probelm?
Did I blow my amp? I tried unplugging all the wires from the amp and replugging to reset... I've checked all the fuses and they are all good..
Do I need a new amp? I'm planning on buying a 12'' Alpine Type R sub and amp but that's a later project.. I just want freaking sound!

If anyone that is experienced or has had the same experience and has solutions i can try before i'm spending another 60-80.00 for best buy to look at it would be greatly appreciated.
