When I was reading the service manual.. or some other manual, i forget, it said that nissan navigation systems use three things to determine your location on the map.
1. direction of car. (compass-type function. checks any turns made, etc.)
2. GPS
3. Speed.
I'm guessing that if any one of these things are missing, then the navigation doesnt work correctly. but that sounds like a small price to pay.
does the nissan nav take voice commands while in motion? Or is this not a viable alternative?
OK... first I'll answer the question of what get's turned off when in motion and what my Hack turns back on!
There is a long list of things that are disabled while moving. I have some pictures of my Nav. System that I will use to try and point out what you can/can't do while driving. Anything that I don't have a picture of I will just mention at the end. If I miss anything somebody let me know!
1. This is a picture of the CD screen. While in motion both the "Folder" and "Track" buttons are disabled.
2. This is a picture from the "Folder" screen. If you happen to be in this screen while in motion, the up and down arrows that let you move around are disabled.
*The same thing happens on any screen with the Arrows... if you aren't stopped, you can't scroll. This includes, your address book, destination lists, POIs, etc.
3. This picture is the "Destination" screen. When you are moving you can't use the "Street Address", "Points of Interest", "Other", or "Change Region" buttons.
4. The other things that I can remember off of my head are just the voice recongition prompts, but that's just scrolling, and the phone tools (soft keypad, time display, etc).

You are right about how it computes your location on the map... the three signals are used to figure out your location. Specifically they are:
1. An angular velocity sensor (gyroscope) - used for high-precision, low speed, vehicle positioning. (This is located within the AV Control Unit)
2. GPS signal - Used for low-precision, higher speed, vehicle positioning. (The signal is sent from the GPS antenna to the AV Control Unit through a dedicated connector on the back of the GPS Unit)
3. Vehicle Speed Sensor - This is used for motion on the map during normal motion. This is the least important of the three signals. There are about half a dozen ways that the service manual details how you could end up "off" on the map because of this sensor. This is the sensor wire that I spliced a switch into.
Here is a brief primer on how the AV Control Unit determines where you are on the map:
As far as voice control goes, it is there, but as I have said many times, the response time is too slow, and it just doesn't work as fast as I need it to, if I am going to rely on it while driving.
Believe it or not... I was brave/stupid enough to take the whole thing out and apart to see if I could get access to the software. That was the mod I originally wanted to make... get rid of the "I agree" screen, and just permanently disable all the "safety" features.
Unfortunately, the thing is put together in a way that makes it nearly impossible to get to anything without some seriously specialized tools that I didn't have with me. I should have taken a picture of the finisher piece that went with it. But I have to warn you, whatever it is like, I am pretty sure that you can't just retro-fit these pieces to the lower models and make it work... there are a ton of differences.
You'll have a lot of crap to buy if you want to make it work... there were about 1000 little pieces that all worked together to hold that unit in there. But it is do-able. The only thing that would worry me is the lower piece. You have a storage bin there, and I have the CD Changer. The problem is that there are some brackets that won't fit without some modification. But those brackets may or may not be necessary.
You da man! I haven't been on here in a couple of weeks and I am glad to stop by and see you got around to this project. Now I just need to suck it up and do the same to my car. The disabled buttons are just driving me nuts.
It's really awesome how well it works. I am planning on going by the Nissan dealership to get the button today. It's going to cost me $30 for the switch I want, but I figure that's a really small price to pay for it to look perfect. As soon as the switch comes in (they have to order it), I'll install it and post up more pics. Then it will really be awesome, and while it's apart, I may or may not try to hack the rear-view camera.
<<<please help>>> install question and help on installing
I just bought a new 2007 2.5SL with bose and love it, the CVT is great.
I have my ipod hooked up to the aux jack and it sounds very good.
What I want to do is run the 3.5mm cable out from the jack and in-between the radio and side panel.
From there I want to run the wire through my center console (under shifter and cup holder, etc.)
I want the cable to come up through my center glove compartment.
It would look sweet and very close to factory, plus there is a power adapter to charge my ipod.
I am very tech. savy and have installed car audio for myself before.
Could someone please shoot me in the correct direction as to how to install this. thanks.
