Aftermarket Head Unit Questions

Not sure how many differences there are between my c and your regular prius, but given that I used references for a Tacoma truck I don't think it's going to be that different...

Anyway... I removed the stock microphone pod from the ceiling, gutted the assembly, installed the aftermarket mic in the shell of the factory unit and then reinstalled it in the ceiling- it looks original.

Then I trimmed the mic wires out of the harness behind the dash and spliced them onto the aftermarket mic plug, and plugged it into the back of the new head unit.

In other words, I'm using the factory mic mount and trim and wiring, I just replaced what was on each end of the wire.

Recycling the gps antenna is possible, but that would be really hard to prove and plan in advance. You should plan on that session being open-ended for timing and results since it may take a few tries with different cable adapters.

That said, lots of aftermarket GPS antennas work fine when you just glue them to the underside of the plastic dashboard. GPS signals will have no problem coming through the windshield glass and dashboard plastic.

 

My 2016 Prius w/ Nav and JBL, I replaced my stock radio with W4400NEX and using GPS adapter(ACC-SAT-TO2) to retain the shark fin antenna.

This GPS antenna adapter package has 3 different type of adapters, Pioneer, Alpine and Kenwood will be supported, there’re more but not so sure what brands. For my case it works.

 

I just did a 4400NEX install in my '18 Prius Three the last weekend.

I mounted my microphone right between the two visors, to the side of the mirror. It is an amazing improvement over the stock mic (not even sure where that was). The other party can hear me crystal clear during calls, etc. It simply works wonderfully.

Unfortunately, I didn't have much luck with reusing the existing GPS antenna. I used the ACC-SAT-TO2, and I thought I had it all connected properly, only to find out during my test drive that the Antenna status shows "NOK". Using the phone GPS with Carplay has been quite a disappointing endeavor. I can't wait till this weekend to try and fix this. If it means I need to use the Pioneer GPS unit, well, it won't be the end of the world - as I've heard it is better than the stock GPS unit. :/ I really want to avoid that scenario.

 

I found out why my GPS isn't working. Such.a.dolt. :/ Sorry.

Glad you got it all figured out - not sure about your question though. I haven't messed with mine too much yet.

 

Hi JerryxSara, do you mind posting a list of your install. I also have a 2016 Prius 4 w/ Nav and JBL... looking to replace my stock radio. I just wanted to know what works and what didn't work on your install. Thanks for your help in advance.

Yes, my Prius has JBL and Nav, the GPS antenna can be adapted.

 

Hello Jerry, did you replace the factory Bluetooth microphone, or can you keep it via maestro RR? Kind regards from Austria.


iPhone ?

 

Hi MichalGocl1981,

I didn’t replace the microphone and I’m using the one came with the head unit, just use a double-side tape to attach the mic, I knew some people route the head unit mic to the location where the factory mic is.

My friend told me that the new mic provides clearer sound than the factory mic.

 

Hi JerryxSara,
Can you detail what car functions you lost ( hybrid monitoring, maintenance info, door/window settings, etc)?

Thx

 

The hybrid monitoring won’t display on the head unit but still display on the cluster, the maintenance should be able to show on the cluster but I’m not so sure. The only thing will lost is the compass and turn by turn nav if your car equipped with nav.

D/W setting can be supported by Maestro RR and access it from the head unit.

 

Hi Jerry @jerryxsara -
Would you mind posting a picture showing us where/how you mounted the microphone? thanks!
