guys, i'm working on a backup camera for my 5, and will be doing some footwork to get a good price on the materials needed to do a decent job. Of key importance is the video integration module available from PAC - I think it retails at 350 and i'm refusing to pay that much. I called a supplier here in Vegas and will try to get them for wholesale which should be around 199 each. If i get a volume buy going, i can probably whittle that down a little more. Then all we need are some decent 108 degree infrared ccd's which I am finding on ebay for about 35-40 each. I'll try to find a local wholesaler for these too...making the full kit just under 300 shipped.

requires 31mm hole (typical trunk lock hole) and a power source (just tap the reverse lights to power it up. The IR led's will turn night into day when backing up, and at least on the Mazda 5, this install is going to be a SNAP.
Whatcha think?
