I think that's a very good deal.
Check the breakdown (all items brand new):
AVIC-Z110BT (from eBay): ~$1150
Back-up Camera (depending on which one he is using): ~$50 ($1200)
iPod Cable (CD-IU50V from eBay): ~$20 ($1220)
Steering Wheel Control Interface (from eBay): ~$50 ($1270)
XM Tuner: (from eBay): ~$90 ($1360)
Installation (depends on where you go but most places around here charge like this):
- In-Dash: $100 ($1460)
- Bluetooth Microphone: $20 ($1480)
- Back-Up Camera: $50 ($1530)
- iPod Cable to Glovebox: $20 ($1550)
- Steering Wheel Interface: $50 ($1600)
- XM Tuner Add-On: $65 ($1665)
- Dash Kit: $10-20 ($1675-$1685)
- Wire Harness: $10-20 ($1675-$1695)
That's all eBay pricing which has NO warranty.
You are getting (which I am assuming) full warranty on all the products and the lifetime workmanship warranty on the installation (I'm assuming the place you are going to follows the same warranty guidelines as the 3 shops around my area).
I definitely think it's a great deal.
