Change Drawer in Dash busted during AVIC D3 install....what to do?

I hired a dude to install my Avic D3 into my 06 Audi A4 (more on the Avic stuff in a sec) and the sole casualty was that he busted my change drawer. Maybe it's not called the change drawer, but it's that compartment next to the hazard light that opens and closes nicely. Put what you want in there...

What's busted was the spring that operates it. He simply told me, "I broke the spring, I'll get you a new one, and fix it ASAP." I know he's not gonna come back for just that - so I'm interested in knowing what my options are. I've not messed around with it, tried to take it out, or anything yet.

Is there really a spring that I can replace and get this thing running again? Can I order JUST the spring, or am I going to have to buy the whole assembly for some ridiculous price? What's the best thing to do here?

Thanks for that -

The AVIC installation went OK, but I was left with a NASTY NASTY hum from the rear speakers when the unit was on, and it got louder when I turned on the headlights. After two hours of screwing around in there last night I figured out that he hadn't connected the negative wires to the rear speakers (and amp) so once I connected those the hum went entirely away.

I now have the AVIC D-3 hooked up with the Bluetooth adapter, and the iPod adapter. I added a small amplified bazooka sub in the trunk to round out the bass. I've used the AVIC for a year in my last Audi A4 (2004) and I really like it. The bluetooth is new for me, and works really well - downloaded my entire phonebook to the unit from my blackberry in a minute. It automatically pairs with my phone when I enter the car.

If anyone needs assistance in troubleshooting an AVIC d3 install - let me know. I've done this twice now, and pretty much have had problems everywhere. I'm really glad to have it all working. Now if I can only get the change drawer fixed....
