    Hello, how's it going, group? Greetings to everyone, and thanks for creating this group. I have a question.
    I replaced the original radio in my 2nd-gen Prius with an Android one, and now the parking system (IPA) isn't working. I installed the 70-ohm resistor, but it still doesn't work. Can someone enlighten me? Thanks!

    You might be mostly on your own with that one. IPA was not a option in the US where most of the participants of the Gen 2 forums are so have no experience to share with you.

    Hey guys! Just in case if someone take a look by google. I found the solution but you will not like it... Is a little bit hard.
    I will try to make this easy:

    1. Remove the original radio because it needs to fit underneath, behind the Android radio.

    2.You have three wires from the original radio, and the speaker wires connect directly to the new Android radio. We need to extract the steering wheel control wires, which come from the 20- or 25-pin connector (I don’t remember exactly how many pins it has). In any case, you need to disconnect the following three wires, starting from the pink one and the other one that is white, and connect them to the steering wheel control buttons of the new Android radio. (You can skip this step if you don’t have a radio with steering wheel controls.)

    3. From the 10-pin connector, we only need three wires (photo attached): ground, 12V+, and ACC12V+. These need to be powered by bridging them with the corresponding wires on the new Android radio.

    This way, the car retains all its functions, and you get a new radio!
