Worst case just threaten them w/ a return. I'm sure they'll take care of you.
As for me I just picked up the same components as THE OP. Since I already have a backup camera I figure I'll unload the Pioneer camera on ebay. Then break even on the Pioneer CD player by doing the same plus with it get the benefit of the free $30 ipod cable. This reduces the overlall cost by another $150+.
Afterwards this'll drop the price of my Avic-D3 to $850-$150= $700!!
I did one better. I noticed they gave me a $30 gift card with the deal by purchasing the Sirius tuner. I had them immediately apply the gift card to the CD-SR100 wireless steering wheel remote.
They can't ship it together due to the gift card, but as soon as my initial order ships, the next day they'll apply the $30 gift card and all I had to pay was the $9.99 balance for the remote. No extra shipping charges.
I worked with Jodi 1.800.388.2911 X4706. She was able to apply both the promotional code and $20 referral code.
If anyone needs a referral code, you can use mine:
$20 Referral Code: pu182-09tqa-puw8t
15% off Code: 3A185
The other important thing to consider is that Crutchfield is a Pioneer authorized seller. This means your D3 from them is covered by a 1 YR manufacturer warranty.
eBay purchases are not covered by the manufacturer and either have a shorter warranty period, or are covered by some 3rd party that can take weeks for repair.
One more thing. Since you're buying 2 headunits, you also get 2 sets of FREE vehicle specific installation accessories along w/ vehicle specific instructions to install your headunit (dash kit, vehicle specific wire harness, antenna adaptors, etc) Just be sure to put in 2 different vehicle types for each head unit. And with Crutchfield, you get free live technical support to help identify your VSS, reverse, and all other wiring.
Hope this helps you folks!
