Keeping Prius Car options/settings if I replace Stock Head Unit?

I suspect you will keep your settings, but be unable to see them or change them if you switch your head unit.
This is why I decided to keep my head unit, despite it being a POS.

I got a MS-8, and I am very happy with it.
It does have an aux in, and you can hook an ipod or other music player to it.
My problem is I really like FM, and I know of no first rate FM tuners that don't include a head unit :-(

 

Sure I replaced all the OEM speakers, as they are worse than useless.

See weasel.com: 2012 Toyota Plug in Prius Stereo for all the details

The MS8 tunes the speakers to have a flat response in the car.

 

Thanks a lot for starting this thread. I was looking for the exact same information prior to buying a Prius, to determine what sound system option to pursue.

Sounds like overall changing the stock head unit isn't a good idea if you want to keep those functions, right?

 

I wouldn't gamble on a new head unit. Most of the locks can be disabled with after-market modules.

 

A DSP or amp with high-level inputs (a "good" amp like JL Audio, the digital ones) is your best bet. Me, I just replaced the front speakers with a Phoenix Gold 6.5 component set with passive crossovers and it requires me to turn the volume higher on the OEM head unit, which is expected, but it's 100% better for SQ in my book.

 

A Metra 72-8104 Speaker Connector will convert the Toyota speaker plug to spade plugs. Giving you the ability to use any speaker of the appropriate size.

 

I'd like to get a replacement for my 2012 Prius, but have the same thoughts the OP has. I'm hoping that when Toyota comes out with a "CarPlay" compatible unit in their next models that they will allow older models to get the unit as a replacement. This assumes they are the same size and that Toyota cares what we, who already are owners, want. Looking at the current head unit replacements from Pioneer and others, gives me the impression that much of the Prius's data/graphics would be lost just for the sake of a better music interface, or the free Nav available from my iPhone 6.

 

Hi folks. Apologies for the bump, but I have the same question as the OP. I’m hoping that with three years later, someone might know of a head unit that would be able to keep car functions, if possible. Thanks in advance!

 

Since you used the search feature, I'll provide an answer

Tech steam can also change the car options such as 30/60/90 seconds low beam off delay, driver side only unlock, and more options so you can dump the stock head unit and still access those stock HU options.
