    No way. :oops:

    Separate "television camera ECU" required.
    Just found it was mentioned in 05-1896 doc of Prius Diagnostic Manual.

    FORGET IT

    Is Japan the only place that offers the backup camera?

    In browsing the schematics of other Toyotas that offer a backup camera there is mention of a Television ECU. I wonder if, for example, the Sienna Television ECU might work in the Prius and if so if it might plug into the head unit or the NAV display. And then there's the cost...

    The blue plug on my package 8 nav system is empty. If we can figure out which is the video input pins on that connector, if it is the right connector, then what's wrong with using a generic 12vdc cctv camera from any source. Mount it INSIDE the hatch looking out through the lower window. Power could come from the back-up lights so it is only energized when the car is in reverse.

    So I assume this means to even consider this, one MUST have the NAV? We Canadians don't get the NAV option.

    Hmmm intresting,

    This cable used here, has a video input and hooks in next to the back seat?? Maybe were looking at the wrong end of the car? :)

    Seems worth pulling off the panel to check, but it looks like the same plugs as our underseat DVD/NAV system and the blue plug on the cable looks like it should fit into the blue plug on our DVD/NAV system. Interesting find though.

    Been there, seen that.

    This is Automatic Parking Assist ECU and it's available only in Japan...

    I found some interesting information regarding the camera option from some toyota documents. Due to copy right laws, I can't post this information here, but I can tell you...

    The ’04 Prius uses 3 types of com links in order to slim down the wiring harnesses. Of interest is the AVC-LAN (Audio Visual Communication), which networks the ECUs of the avs and the av devices, and maintains links between the devices and the ECUs

    I believe the camera would have to be on the AVC-LAN for the nav computer to see it. There are several references to video capable devices listed in the hardware address list in the document.
    Device Name / Address
    1DIN TV / 128
    Camera -C / 1AC
    TV-Tuner / 230
    DVD CH / 250
    Camera / 280
    TV-Tuner2 / 1C2
    Rr-TV / 1B0

    I believe the Rr-TV is the rear backup camera device.
    The AVC-Lan is essentially a local area network running a differential voltage circuit @ 17.8 kbps over twisted pair. On startup the system checks for devices on the network and identifies the units. The software may or may not have the options to support these optional devices. Putting the NAV into diag mode may shed some light, but the diags may only show up if the devices are recognized on the lan. I found this information on the TIS site techinfo.toyota.com doc RM1075U. I would be very cautious in connecting any devices or equipment to any open connectors or the AVC-LAN or NAV computer. An overload could conceivably run over the network and blow out many ECUs on the chain. I'm not even certain what would happen if the nav computer could not identify the protocol being transmitted over the line even if one were to build an interface. I believe in light of this new information I'd look for the OEM camera and ECU for the prius. Since it's clearly documented and looks to be operation in Japan, It may be only a matter of time before Toyota decides to release it in the US. Who knows. Maybe one of you adventurous owners out there may find a prius rear cam and instructions on how to install it. Anyway, I thought the group may be interested in this information


    Regards,

    Carlos
