Nav Upgrade Options for III w/Factory Nav

People buy aftermarket units as an alternative to paying $$$ for factory navigation. Read the posts and you'll find aftermarket units have their own set of "issues". Might be better then factory navigation in some areas but inferior in others.

You could call Crutchfield. You'll probably have to use a JBL amp turn on unit. Not sure what other wiring you'll have to work with. I have no idea if you can use your existing backup camera.

Units like the Ottonavi aren't "plug and play" with your factory navigation.

 

When you put in an aftermarket stereo/nav, several of your factory items will stop working (bluetooth, aux port, etc.), but the new stereo will have it's own port and connections so it evens out. Backup camera should work fine once it's wired to the new stereo.

The biggest concern is the JBL speakers. In older Priuses, I was told that aftermarket stereos would kill/blow out your JBLs. That may have changed with Gen III, but I'd ask Crutchfield or the shop where you're going to get the aftermarket stereo installed.

Cheers!

 

A JBL amp "turn on" device such as the TATO uses the pre-amp out from your new HU. I don't see how that would blow out your JBL.

A few HU, and the Metra steering wheeladapter harness, will support the factory AUX jack.

I don't know of any aftermarket HU which supports the factory BT Mic.

I haven't the slightest idea if the factory camera is easily supported. Does the factory OEM HU have a standard video input for the camera? Do you have any definitive information?

I don't think there is a custom harness for the OEM Navigation radio. I suspect there is very little demand.
