Gen 2 Prius (Audio/Electronics) :: Upgrading Head Unit Might Make MFD Unusable?
Jul 27, 2014
I've got a 2007 with Nav and was thinking of replacing the head unit with an Alpine INE-W940 or something similar/better. I spoke to Crutchfield, and they told me that this install would make my MFD unusable, and I'd have a blank screen. I am not certain if the tech meant that it would be useless for navigation or radio/cd control, but still function for other uses like battery monitoring and consumption.
Even assuming that it would still function for car information, etc., I was wondering, using perhaps Lockpick 3 to mirror the display of an aftermarket head unit/nav system to the MFD. I'm thinking this would be a really useful hack.

No audio in the head unit, the service menu is not displayed diagnostics audio.

My JBL head unit keeps dying. My 2011 Prius Three, not III, is currently on its 3rd head unit, and this one is dying also. About once per year, the head unit starts displaying gibberish on the LCD, often with horizontal lines marching upwards. As the problem persists, the display gets worse. Finally, the buttons start malfunctioning. Pressing the power button might eject a CD, pushing a radio preset button might switch to CD, etc.

I installed a alpine power amp - keeping the factory head unit. It sounds much better but I lost the illumination of the buttons on the head unit. I used the Metra connectors and matching the colors and adding wires to connect with the amplifier. There is 12 volts going to the head unit on the orange and white connector but no illumination of the buttons.
2012 Prius v, no JBL, with nav.

Within the week the head unit has started to glitch out. Doesn't seem to be any real issues with any usability- at least yet. I have a 2011 Prius II.

very faint but it's there. Kenwood Exelon head unit and 5chan amp. Noise varies a bit with throttle. Equipment is all decent / good quality. Is this something I have to live with as a hybrid owner? I have a short ground from the amp in the spare well area at the factory battery ground point. Have a dead silent amplified system in these cars?

I have a 2010 Prius II that I am attempting to install a Pioneer AVIC-5000NEX head unit into. After following the instructions in the sticky thread the head unit itself works perfectly, but the car beeps constantly when turned off, and if I exit the vehicle the screen says key not detected. If I remove the Pioneer head unit and plug in the factory everything works great, but anytime I have the factory head unit removed I can not leave the vehicle without the key not detected error.

I figured out how to get the text message function to work on my head unit. It was a setting on my iPhone, under Bluetooth it was the "show notifications". Then all of a sudden bam any texts I get while in the car pop up and the HU will read them aloud, also there are a bunch of quick responses.

I do not have the Nav/JBL head unit, just the basic Gen III Prius II head unit, and would like to disable the speed sensor lock capability of the unit, like others have done with the Nav units.
If there is a plug-n-play defeat/bypass kit for this HU? There are some "fuel efficiency" windows in the HU, would I loose any of these functions/displays with such a bypass?

I'd like to upgrade the head unit to something which sounds a little better and offers better A2DP streaming (the Australian Prius I-Tech doesn't offer stock Bluetooth streaming and the GROM Audio unit I am currently using to achieve this is temperamental). Everything I read suggests that you loose IPA if you do this upgrade, and while I know most people probably won't miss the feature, I personally find it very useful.

I have a 2012 Prius Two, a monitor with Bluetooth capabilities. I use the Samsung Galaxy Note II with Sprint on Jellybean Android.
I have tried numerous music players on Android and here's what happens:
Music plays fine. Bluetooth paired perfectly. Randomly the entire head unit will reboot. There is no pattern. It happens after about a minute and a half. It shuts off and comes back on.
I do not have an AUX in unfortunately. When I tried my wife's HTC EVO 4G on Android It worked perfectly. Only Bluetooth.
I tried to install entune. No dice. it says that ny VIN is invalid.

So need rims and a stereo upgrade. I am getting my Prius on the 28th and want to do the stereo upgrade immediately. My stereo shop here in Tampa is saying that they don't want to do more than 1 amp because the draw could be too much and give me problems with the electrical system. SO I wonder how much power all the things in the car take up while running and then how big an amp (or two) can I put in there? How many Amps (not amplifiers) do I have left over safely for use in upgrading the stereo?
I have a Pioneer Avic stereo (not sure the model at the moment but it does DVDs, CDs, and NAV. Has 5v pre-outs which are nice. I also want to run a set of
Up Front:
DLS Ultimate Iridium 6.3i components up front
6.5" woofer, 3" midrange, 1.1" tweeter. 100w RMS per channel
I thought to put the woofer in the door, the 3" in the dash like rrolff's squaker install (I have the NONJBL audio too). and tweeter in the stock location.
Rear:
Possibly component set in the rear doors but haven't really decided yet.
I have a set of 5.25-inch components that can go back there from DLS as well Figured why not use them. but if there are better ones out there I am not opposed to it.
The amps I am considering are both JL One is the HD 900/5 which is 100x4 + 500x1 or the XD 700/5 which is 75x4 + 300x1

Do not like having the nav screen always be on especially since we rarely use it. Would much rather look at the audio screen. How do I make audio screen default?

Any way to access the nav to play video on it via RCA? I did this in my Acura tl with a module I purchased.

I've got a III and looking to put on an external GPS unit. I have looked over my dash every time I drive and thinking the texture doesn't allow suction cups to work. How do you mount ?

I just purchased a 2008 Prius and love it but I'm having the dreaded XM signal dropout. I would like to move the antenna from the from dash to the roof behind the regular antenna. I'm having trouble locating the XM radio unit. I heard XM unit is under the driver's seat. The unit under my driver seat is labeled 'navigation'. Is this the same unit as the XM radio?

on my sub amp the wire out got hooked up my wires to my car speakers while replacing the battery and it went boom and there was a smell of burnt electrical. Now I don't have any sound coming out all in my car. I'm trying to figure out if it is a fuse problem or if I blew out all of my speakers, but before this happened I disconnected the center speaker by the screen because I wanted a more stereo sound in my car. I reattached the center speaker recently and still no sound. I looked at the fuses underneath the steering wheel and I couldn't find any blown fuses.

I can receive messages and the HDD unit reads back the messages from my iPHONE. But when I hit reply and pick a preformatted text like " I am driving. Will call later" and hit SEND, it gives me an error. I have not so far been able to reply to any incoming messages.

I have a 2005 Prius and need a new navigation unit and I found a place I can order online, however I did something not so bright I ordered for a 2007 Prius. I need to know if a 2007 navigation unit will work in a 2005?
