Is installing an aftermarket radio possible?

    [​IMG] I got an 05. Metra 70-1761 wiring harness does not fit. (See attached photos) I can't find a harness that does fit. To add insult to injury, the A/C and MPG traking doesn't work unless the OEM radio is installed. What do you suggest I do to install an aftermarket radio while maintaining all the original functions? Just splice the wires and install it?

    Got my pioneer installed at Best Buy. They did a great job using the interface harness and everything works
    Including all the steering wheel controls. So there's a off the shelf interface for a g2 available no splicing necessary.

    Got the front speakers replaced with pioneers too and the system sounds 100% better.

    I had an issue with the MPG tracking after my double din install until they put a resistor somewhere. I bet if you search there is a thread about it.

    So what your saying is that I need one of those steering wheel harnesses to accomplish this?

    You need an ac retention harness that plugs in behind the radio

    It's possible! Either use the resistor that came with the Metra harness or use the radiopro4.

    i bought a scosche adapter harness and the metra axxess for my '04. the scosche kit had the resistor preinstalled. it worked perfectly. if you have the jbl, you got a whole nuther problem and need something called a tyto adapter kit. I forgot exactly what it is because I decided not to spend the money and just kept the jbl in my'06.

    My car has a JBL stereo system. I needed to buy a metra TYTO-1 harness and 68 ohm resistor. Thanks for the help.

    Yep a 68 ohm resistor was required, the instructions on how to use it came with the JBL specific harness.

    There are two options, mounting a single DIN below the factory one behind the push-out door (See this thread: Stealth install an aftermarket stereo in Prius | PriusChat) or replacing the facory system with a double DIN (or maybe larger) and using an adapter kit. If the stock radio is disconnected a resistor needs to be installed as noted by others. See the stealth install thread for a lot of tips on wiring, IIRC it covers how to do both setups.
