z1abroad,
I don't know how GReg learned of them being in or out ot stock, but for me it was as simple (if you live in the US) as going to
www.circuitcity.com and entering in the model number AVIC-Z1. Based on your US zip code, it will bring up about 10 stores in your area. If that list is not big enough, you can ask it to look for more stores and it just keeps expanding outward (North, South, East and West). Being in the Baltimore/Washington metropolitan area, there are 42 Circuit City stores within a 100 mile radius of me. The good thing about life in Maryland is that 100 miles from Maryland has me in D.C., Pennsylvania, West Virginia, Virginia, New Jersey and Delaware. In other words, lots of stores to choose from when one is sold out. There are 28 Tweeters within driving distance and about 37 Best Buy stores plus a ton of mom and pop and specialty shops that sell items like an AVIC-Z1. As of right now, (1:22 p.m. EST), there are no more ND-BT1s in the area. The last store was the Marlow Heights store that had one for the longest time. Don't know what took people so long to get down there and buy it. :D
