New to the Prius (2 weeks, tomorrow) and new to the forum! We have a base package 2009 Prius, and I bought the Vais SL2i-UP to install for my iPod. The Vais owner's manual and previous threads in this forum all show that the port in which one is supposed to plug in the interface is on the left of the radio, behind the tuning knob. I followed hybrideyes' directions for installation but when I tried to plug in the interface, I found that the port is already filled with a 20-pin plug. Does anyone know where the 12-pin plug is supposed to go with this configuration? Is it still do-able without taking the radio out of the dash? Thanks!
As you look at the radio FROM BEHIND, the left-most connector is 20 pins, the one to its right is 12 pins. I believe thats the one you want. Good luck with your project!
