installing used entune & navigation touch screen

I don't know if you can, but I would spend my money on an aftermarket unit. The built in system is good but for the same money you can get a much better product. You could check ebay for the OEM navigation unit but not sure where you would get the buttons. Not sure if there is any wiring issues you may run into. Someone may have more details as to what you need to accomplish your goal. Good luck

 

Member wmo168 do this with the Nav Unit only, there are some extra wires that you need to connect in order to work. Can ask him. here's the link of the topic:

Wiring Diagram for Factory Nav Radio - looking for wires that feed(Energy Consumption and Trip info) | PriusChat


I personally have the voice command steering pad (yes you have to replace both sides of your existing ones, since the wiring is diferrent) and now waiting to buy a Nav Unit to see if it works.

 

nop, since I never tried on a touch screen.

 

I got everything research and working (Sat, Backup Camera, GPS) but I didn't ever bother with voice command changes as I never use it in my BMW too.. I know Rolopr is doing that and I gave him the wiring diagram to him.

Yes, a used C3/4 radio will work in a C2. just need to tap into 3 wires on the harness. It took me 1 months to get everything figure out but I am glad to help anyone here. I am using GPS and listening to XM radio daily now.

 

Installed Nav Radio and Steering wheel pads, Voice command works with the radio, but for some reason the Disp & Trip on the right steering pad now working.

 

I leave the existing C2 Steering wheel control alone and the Disp and Trip on the right never had issue. You don't really need to replace the right side do you? You just need the Voice Control on the left... Perhaps you loosen something when you take the wheel apart?

 

Must have to replace both sides since the plugs from the one on the PC3/4 pads are different from the PC 1/2 ones in order for the voice command works.

 

Fix steering wheel pads, now everything works on the pads 100%.

In order to use it on the PC 1/2 you need at least the left pad that have the voice command button.

1. Remove everything ( including the black buttons shown) from the left pad pf PC 3/4 leaving only the voice command and bluetooth buttons (pad).


2. Disconnect the board of the removed pad and replace it on the existing pads of PC 1/2. (see that have 3 black buttons, PC1/2 only has 2 buttons)


3. Remove everything on the left pad on the PC 1/2 (without VC button) - 3 bolts only and installed on the PC 3/4 pad now (with VC button).

Activate first the Bluetooth and cancel, then push the voice button for a few tries until the HU recognize it.

 

whered you get the 3/4 buttons? ebay?

glad you got it working

 

Yep ebay a while ago, search: prius c oem steering wheel.

Remember you need the left pad complete only. If you get both eee keep the other one as a backup if the existing pad is scratched

 

Great find! Now we have a 100% OEM NAV Retro on C1/C2 solution.

 

Did you need to install an additional antenna to get the GPS to work? I have a 2 and just purchased an OEM navigation headunit from a 4. From what I've read, it's essentially plug and play. I do NOT want voice command. I can not stand repeating myself. I am just wondering about needing an antenna for the GPS.

 

Yes, you need and GPS Antenna for navigation purpose only, you can get it on Ebay, same as I do, even you can buy the Sirius XM antenna too (I don't need it since most of the time I used Itunes Radio )

I bought this one:
Toyota Car Navigation Units GPS Antenna 09 | eBay

You need to trim the lower edges, in order to plug in to the radio.

 

Thanks so much. Gonna order that now. My nav unit should be here this week.

 

Cool.

 

Where did you run the wire and mount it at? Trying to keep it looking clean.
