I spent an inordinate amount of time studying all the issues here with the D3 and the bypass, the BT issues with phones, the route inconsistencies with the Nav, etc...
I bought my unit on Ebay and the price was good enough that I could also buy a no questions warranty from Square Trade and I still came in much lower than Crutchfield with the new rebate from P. I did buy a Sirius tuner from Crutchfield so I didn't get off totally retail free. I bought it from them because they insisted it was new. I could only find refurbished on Ebay. The price wasn't that different anyway so my peace
