I had some problems interfacing my I2C device. (SDA to D4, SCL=D5 , 10K pull-up installed.)
so I tried Arduino Playground - I2cScanner
- no device found.
I tried a logic analyzer on the pins, both are just high all the time.

A4 and A5, not D.....
edit.... just noticed you said a Nano, I only ever use a Uno. Maybe different?
more edit... I see here it just says 4 and 5 without qualification, so I guess it means A4 and A5.
Thank you A4, A5 worked instantly. not only is the page missing this information http://arduino.cc/en/Main/ArduinoBoardNano
but some of the pinout images found by google ae incorrect. https://www.google.no/search?q=arduino+nano+3.0&client=ubuntu&hs=cl2&channel=fs&source=lnms&tbm=isch&sa=X&ei=5-SiVLemFqfnygOEnYDQCw&ved=0CAgQ_AUoAQ&biw=1920&bih=985
How do we get the official Nano page corrected ?
