Here's a 4th option which uses the "DEST" and "MAP" buttons that come with the car to enable and disable navigation and phone inputs. Basically...
Actually I think the consumption bars are OK. It was a little hot today and I think the mpg were lower due to the A/C.
I've confirmed that cutting this wire and injecting a square wave of the right frequency does allow access to navigation, phone and voice features...
On the 2004, I found that substituting the speed signal with one equivalent to ~3mph allowed access while moving without triggering the secondary...
Glad you got it working Brian. Yup - should have said pin 6 instead of pin 5.
Hi Brian, Just noticed that the BT only schematic doesn't mention how to set the 2 variable resistors. Hopefully you noticed the equivalent on the...
Those are just unused NAND gates and comparators. The inputs should be tied to something to avoid surprises, but the outputs don't go anywhere...
Here's the schematic of the BT speed sensor auto defeat in case anyone wants to build one: http://www.wb5mrn.com/prius/bt_only_schematic.jpg
Yeah - it has been a while since I checked in here. I've always joked that while a backup camera is nice while parking in a tight spot, what...
Those of you with a video input for your Prius (such as for backup cams) might be interested to know that some cell phones have video output which...
Anyone know whether we can configure this Coastal Nav kit to just do the I agree part? I find it quite annoying that it has about 10 seconds...
How come my VIN has 9 digits after the 20U but the pdf document list of VINs shows 7 digit numbers? Should I ignore the first 2 or last 2 digits?
The eclipse OEM camera is very likely to work with the CoastalTech system. But I guess we won't be certain until someone hooks the 2 together....
Geronimo, In the 2005 US model, the nav unit is made by Denso and sits underneath the drivers's seat. This photo shows the great similarity...

It seems very likely you could grab the analog signals right before the power amps and rewire them to go directly to the output (for external...
Assuming you're looking for schematics of the innards, this might be of interest: http://www.priuschat.com/forums/reducing-t...amp-vt7812.html....
Since the upd6708 looks hard to get and incapable of monitor all traffic on the AVC-LAN, I've started designing a circuit to interface between the...
DanMan32 - It's brute force so far with an oscilloscope. But to help know where to look I triggered on the interrupt pin on the 6708 in the JBL....
