That's exactly the quaetion I was gonna ask. Who's fitted what? The one you have looks perfect. Don't really want one and have to ponce about with crappy looking fillets if there are ones that exact same size as original. Not really bothered about phone or sat nav but if it comes with that then great.
What is it?

That is a "pumpkin". this is just a brand name applied to a model and also goes under lots of different brands. Here is one example that looks like it would physically fit - www.ebay.co.uk/itm/GPS-Sat-Nav-Car-Stereo-Bluetooth-DVD-Radio-For-Toyota-Corolla-RAV4-Prado-Yaris/233402091758?you want a unit that is 2Din-Wide (that term does not seem to feature though) and connectors that are "7+5" rather than "6+6"(the 7+5 one is physically larger. Look for a radio that is for Toyotas around 2003 or so. That would give the right connector style and also quite a few toyotas match the 2Din Wide style - RAV4, Land cruiser I think, Celica is the same I believe. |

The usual way for that vintage of head unit is for an adapter to emulate a CD changer. i.e. the aux/bluetooth/whatever adapter will appear like a CD changer to the head unit (You'll get something like CD 1 track 1 appear on the display). The adapter will route audio from bluetooth (or aux or whatever) into the CD changer input (actually called avclan) on the rear of the head unit. It's not a simple audio input, you need some data communications with it, which the adapter will provide. It's usually via a standard (for Toyota) 12 pin connector. There was a change over from a larger to a smaller connector around the time of that particular head unit. Connectors(s): -  Typical adapter: gromaudio.com/store/usb_adapters/toyota-lexus-98-05-usb-android-iphone-car-integration-adapter-kit.htmlsimpler/cheap adapters are available or even build yourself designs, if you have the electronic skills. Hi Shcm.
Do you know if there is any simple way to emulate the control lines without a radio, this thread has prompted me to dig out the old adapter I have, but wondered if there was any way of testing it without having to sit in the car with the radio hanging out of the dash.

Thanks I'll whip the unit out to confirm exactly what connector I've got. Don't want to cock up getting the wrong one. |

No. You'll need something that talks "avclan" protocol on "iebus" hardware. It's not a few simple control lines. It's basically a differential bus, not unlike CAN, but a lot slower. All the audio units are connected to it. As well as the data bus, there is a common analogue audio connection. Everything sits on that too, but everythings' audio outputs stays high impedance, unless it has been selected as the audio source (via avclan traffic). I played with it about 10 years ago and got a fair way with talking to Mr T's sat nav units, but it was never totally finished, other jobs (mainly work) got in the way. It's part detective work to decode the protocol (it's not in the public domain). www.toyotaownersclub.com/forums/topic/118696-rav4-t180-sat-nav/To play, I either extended the avclan cable out of the back of the unit (e.g. into the glove box and the connectors to do that are actually available from places like RS. Or use an existing CD changer cable) www.toyotaownersclub.com/forums/topic/120612-toyota-avclan-cd-changer-connector/Or, I took the unit out of the vehicle completely, to play. You just need power & avclan connections. The Toyota "power" connector pinout is mostly standard (10 or 12 pin connector often shared with the front speaker connections) and with some larger insulated "female" crimps on the end of some bits of wire, you can just slide the crimps onto the pins in the connector @ the back of the unit and apply power from a 12V supply. Mating Connector half not needed. Just need BAT+ ACC and GND. www.tehnomagazin.com/Auto-radio-car-connector/TOYOTA-Car-Radio-Wiring-Connector.htm |

You have the 58812 Radio? then you will have the 7+5 large one (the second one shown in schm's post) also see here for a photo of the rear and a full pin-out list - forum.rav4driversclub.com/thread/91/rav4-58812-radio-cd-pinout |

Some units loop the bus out and back into themselves and struggle to work without it. It's probably to do with "multiple functions in one box" and I can sort of see the logic of it, but not much!

I'll check it out still. The link you give mentions that the connections may be different if a CD changer is present which I have. |

Yeah I've seen quite a few now, I'll be looking at getting something soon. |

not quite the right shape for a RAV4.2 (unless you have a hacksaw I guess?)

Wasn't quite sure when 4.2 & 4.3 changed it said 2006, that's my story & I'm sticking to it.
