Breakout - MPU-6050 SEN-11028 wiring

Hello,

I followed all the instruction but still have no success connecting Sparkfun MPU 6050 breakout board with Arduino Uno R3.
Steps I followed-
Copied "I2Cdev" and "MPU6050" folder form GitHub - jrowberg/i2cdevlib: I2C device library collection for AVR/Arduino or other C++-based MCUs into libraries
Wiring-
VDD --> 3.3V
VIO --> 3.3V
GND --> GND
SDA --> A4
SCL --> A5

then copy pasted the Arduino Playground - I2cScanner i2c scanner script but it says no connection found..
could someone tell what am I doing wrong?
