Pioneer dvd head unit install issues, MFD flickering ect..

Hello everybody I hop I can get some help, right now my whole dash is disassembled and I really don't want to put it all back together until I have this fleshed out.

This is the parts list for the install

Metra radio install kit (brackets, fascia and resistor) model 95-8240B

Pac RadioPro4 RP4.2-TY11 radio interface (to integrate stock JBL amp and steering wheel controls.

Pioneer AVH-X3600BHS (2013 model)

siriusXM interface (haven't installed yet)

I followed the instructions to the letter, I went and updated the firmware in the radioPro and set the Pioneer E brake setting to "on"

set jumper 1,2,3 on for Pioneer radio

Installed the resistor so the ac controls work

Solder and shrink wrapped all connections

Figured out that you need to set the volume on your old radio to max before you disconnect it or the factory amp will be set very low. (this wasn't in the instructions, I found out the hard way by stumbling across it on the internet somewhere)

I have everything working.....but now when the radio plays anything it will play for about anywhere between 10 to 30 seconds and then the sound will quit for about 10 to 15 seconds and then it will repeat that over and over. and that is for every source.

Also, the MFD will flicker on and off as well, (the radio and MFD aren't synced, it flickers on and off at a different pace, also it will default to the gps no matter what screen I go to after a bit of time it will go back to the gps screen.

The only thing I see that might be in question is that I have the Programmable
12v+ Output (red and white wire) connected to the Yellow constant 12 volt wire, rather than the red ACC 10 amp wire. ( but, for my install it is disabled in the pac settings screen (when connected to app with usb on my PC.)

Does anybody know what it could be??? I am throwing some error codes because the dash is disassembled and some things are unplugged. but, would that cause the sound from the stereo to cut out as well as the MFD to flicker on and off?

Thank in advance!

OK, through pain and much gnashing of teeth, I was able to get every one of my issues resolved
Below is the stuff that is NOT in the install manual for the PAC RadioPro4 RP4.2-TY11 radio interface, If you have never installed a radio in a newer car You will need this information or your install will not go well. One more thing, before you do anything else take the radioPro4 set all the dip switches to the "ON' position, connect it to a pc and do a firmware update, you will need the firmware from PAC as well as the PAC app to install the firmware.
when installing the Pac RadioPro4 RP4.2-TY11 radio interface, there are a few things that are not in the manual which will give you major issues if done incorrectly, First, before disconnecting the OEM radio, set the volume to max, then turn off the car and disassemble dash and remove radio. If you don't do that, you will need a windows laptop to connect to the Pac RadioPro with PAC's configuration software while installed in the car and connected to the harness to adjust the OEM amp's settings.
The blue and white wires (called remote out and remote in) there is one out coming from the radio harness, and there are 3 in's, one bypasses the PAC interface device and then 2 that are next to each other on the Pac harness. all these wires should be tied/soldered together, only one actually runs to the amp to turn it on, the other 2 lead nowhere, You tie them all together because there is no easy way of telling which one is the one is needed so Pac suggests to solder them all together. The 12 volt output (the red and white wire) should be cut and taped off because it is not used. also. with the PAC RadioPro4 You do NOT NEED TO WIRE IN A SEPARATE RESISTOR, the radioPro4 takes care of that. adding a separate resistor will result in MFD getting all funky and flickering on and off.

If you have an issue with the volume from the oem amp pulsing up and down On the MFD, you will see it cycle between 45 to 50max volume. if this happens, go into your radio settings and disable your high pass filter. In my car, it fixed the problem but, if it doesn't you will have to disable fade in the oem amp...meaning, you will have to use a windows laptop with the PAC configuration software app while connected to the car to do that. also, after every change or adjustment you will need to cycle the car on and off a couple of times for changes to take effect.

I hope this helps someone, I went through a lot of trouble calling PAC as well as scouring the Internet to get this information.

 

Unfortunately, The volume bouncing is back for me, it seems to go away after driving the car for a little bit but, it is still an issue, sorry I didn't update this issue. I am going to contact PAC again, I did everything that they suggested and I am still having the problem, What I have been reading on the Internet is that this could be a component failure on the Radiopro4, I am hoping that I can get them to swap out the unit, That is all that is left that I can do, also, there is still radio screens displayed on the MFD like FM and the presets, from my reading all those screen dissappear and you should have the radio off screen all the time when you press the radio button on the MFD.

 

That is just wonderful, Sounds like your customer and I have a lot in common. I purchased from Crutchfield as well, I hope I don't have to go to extreme measures to get them to stand by their product. (Pac, that is)

I just have to ask you, have you downloaded the Pac software onto a windows Laptop and connected it to the RadioPro4 while it was installed in the car and powered up, went into the settings in the software and turned off fade (it's a check box) after that you need to refresh the Radiopro4 with the software while still connected to it and then restart the car once or twice. If that doesn't fix it, then it is a problem with the unit itself, There is nothing else to do short of bypassing the Prius amp (which is another headache unto itself.) Im going to call Tomorrow and push for either a resolution to this problem up to and including replacement of the Radiopro4. I'll even give you the name of the tech if everything go's well, so you don't have to explain what the problem is over and over again.

 

The suggestion I got from five star audio was to NOT use the Pac RadioPro4 RP4.2-TY11, It does NOT work properly and to go with the older solution, o the post above from 3prongpaul.
With the exception of bypassing the JBL digital amp altogether, use the "Axxess TYTO-01 for the radio/Amp interface along with PAC SWI-RC steering wheel control interface."

The RadioPro4 just doesn't work properly, If you can, return it. It's trash and Pac has no plans to fix the issues that are specific to the Prius.

 

I had absolutely no problem returning Pac RadioPro4 to Crutchfield, that "should" go pretty smooth.
