Ok, because I am feeling generous and as a way to give something back to this great community of ours, I present everything you wanted to know about your Navi but were afraid to ask.

From the '04 Shop Guide:

1. Turn the ignition switch to ON (II).

2a. If the battery has never been disconnected from the car: Press and hold these keys all at once: MENU, MAP/GUIDE, and CANCEL. Keep them pressed for approximately 5 seconds. The display will then go to "Select Diagnosis."

2b. If the battery was disconnected and reconnected prior to this test: Hold down MENU and ZOOM OUT buttons. You will see the Navi System Link screen. Push the joystick to go directly to the "Select Diagnosis" screen.

NOTE: This ONLY allows access to the diagnosis screens. All other Navi features will be disabled.

3. After the display changes to the Select Diagnosis Items Menu, touch the item you want to check and the check will start. To return to the previous screen press RETURN.

You can test/diagnose the following:

Navi System (Link)
F-CAN (Link)
B-CAN (Link)
Monitor Check
Unit Check
Car Status
GPS Information
Yaw Rate
Tire Calibrate
Functional Setup
Version

NAVI SYSTEM LINK

This diagnostic tests the cable connecting the navi components. Ensure the ignition switch is in the ON (II) position. When the diagnostic begins. a "bong" sound is heard. The system is in a "detecting" mode, and is waiting for all items in white to be tested. This includes the steering wheel TALK/BACK switches and microphone. Push the TALK burron on the steering wheel, and in a normal voice, say TESTING. The Talk indicator on the screen should become green and the voice level indicator should move to the 6th bar to pass. Next touch the steering wheel BACK button. This should cause the CANCEL indicator to turn green.

If all communication lins connecting the system components and the steering wheel/microphone checks out OK then the OK indicator will become green.

If there is a problem the faulty component itself will change to red and ths creen will show NG in red.

Any indications on screen will not change until the ignition is recycled (powered off and back on).

Touch Exit Diag to exit.

FCAN/BCAN TESTS

These are used to diagnose Fast Contrller Access and Body Controller Area Network communication systems. The tests are meaningless without a Honda Scan tool.

MONITOR CHECK

RGB Color

This screen verifies that the display unit is receiving the video (RGB and Composite sync) signals properly. The three primary colors should all be shown without distortion. The combination of all three should produce a central white section. If any colors are missing there is a color signal problem. If the picture has lines in it or scrolls horizontally or vertically, troubleshoot for a composite sync problem.

Gray Tone

This screen diagnoses problems with contrast. You shoud be able to see the changes from bar to bar across the scale. It is normal for the 2 bars on either side to appear the same.

White/Black Raster

White Raster - the entire display must be shown in white.

Black Raster - the entire display must be shown in black.

Test Pattern

Factory use only.

Monitor Adjustment

This allows the display to be centered. Use the joystick to move the picture up down or left right. DEFAULT restores the display to factory specs.

Touch Panel Check

The panel touch sensing systemn consists of a touch sensitive resistive membrane covering the display. Contrarly to other systems using infrared beams, the screen has to be physically "touched" to make it work. The display has the capability of an almost infinite number of touch locations. However, to be compatible with earlier systems, the software only senses the locations shown. Every possible touch button position is shown in this test. Touching one of thses positions should cause the color to reverse and sound a beep. If the locations are off slightly (by less than one touch location) use Touch Panel Calibration to realign the zones with the screen image. If an area does not respond or responds at some other location when touched then replace the display unit.

Note: Unlike earlier screens that used infrared sensors, direct sunlight will not affect this test.

TOUCH PANEL CALIBRATION

Touch the four "+" items on the screen. If the screen responds at some other location when touched, adjust the responded point to the touched point using the joystick.

UNIT CHECK

Display
Performs additional checks on the communication bus between the control unit and display. In addition, the internal display electronic components are checked.

NG responses indicate not good. If ROM or RAM report NG the display unit must be replaced.

Version number is not the DVD version - it is the version of the internal software for the display.

Radio

NG responses indicate you will need to check for a loose audio unit connector.

Navi ECU

NG Response for Indicates
-------------------- -----------
V-RAM or D-RAM Navi Unit Needs to be
Replaced
GPS (Ant) Check antenna wire.
If wire OK, New Navi Unit

IMPORTANT: MEM CLR should NOT be pressed. It erases all customer information, personal settings, GPS orbital data and anything else in memory and is for factory use only.

PC Card

No relevant information.

CAR STATUS

This screen is used to confirm the navi is properly receiving input signals. Signals equal to zero are OFF and those equal to ONE are on. If the value does not match the actual vehicle status then check the wire carrying the signal.

This is mostly technical - if you have a need to really know this section let me know.

GPS INFORMATION

This screen shows the current status of GPS reception. The circular diagram shows the current location of the GPS Satellites (yellow numbers) as they would appear in the sky. The outer circle represents the horizon (0 degrees elevation). The middle and inner circles represent 30 and 60 degrees respectively. The very center of the diagram (90 degrees elevation) is directly overhead. Nearby obstructions like tall bhildings will block satellites in that direction. Thus, you must be in an open area to effectively troubleshoot GPS issues.

Number of Satellites shows the number of acquired satellites, It should contain 3 or more icons.

Current Position shows latitude, longitude, and elevation in meters, If there are less than 3 satellites the elevation can be grossly inaccurate.

Date/Time field shows current date and a time that includes daylight savings time and other offsets entered by the customer in Setup Screen 2 - Adjust Time Zone/Clock.

GPS Detail

By pressing and holding MENU for 10 seconds you can see a screem displaying real live incoming satellite positioning data.

YAW Rate

Controls the position of the icon of the car on the map. Nothing exciting here.

If you play with this screen BE SURE TO SET THE VALUES BACK TO THESE DEFAULTS:

AUTO TUNING: ON

Sensitivity Study: Self Calibrates between 6 and 10

CCW Cal/W Cal/Set are FACTORY USE ONLY AND SHOULD NEVER BE USED. Default in the screen shot is +0.0 for both.

Tire Calibration

Controls your speed of scrolling on the map.

Auto Tuning should always be ON
Level - indicates tuning status - if less than 10 unit is still calibrating
Tire-Cal Tuning and Set are for factory use only. The sample screen shot shows -1.0%

FUNCTIONAL SETUP

Trip Information
Shows current internal values used for computer calculations. Factory use only.

Simulation start is for factory use only. Data save should always be ON.

Trip Calibrate

By holding MENU down while on the Trip Information screen you will see the Trip Calibrate screen. This screen allows you to adjust the miles to empty (vehicle range).

Calc Range - Calculated Value

Disp Range - Displayed Distance on the trip computer. If it reads "0" the vehicle will have enough fuel to travel approximately 20 miles.

Range Tuning - Used to adjust the value for the range to empty. Recommended not to change.

NOTE: Setting the range offset too low (+10) could result in the vehicle running out of gas before the display reads 0. Make changes slowly when changing this value.

Solar Angle - Not used for TSX

Most other features in the test screens are for factory use only.

larchmont

Are you sure about this, Steve?

My impression, very strongly, is that it's significantly more -- at least 40 miles, probably closer to 60. Anyway it would probably be more apt for us to put it in terms of GALLONS, not miles (I put it in miles only because you did). I'm judging from the amount of gasoline that the tank takes at various times (even topping it off), correlated with the remaining range displayed on the Trip Computer.

(Not that we want people to be counting on it, but just for the record.....)

From the Service Manual, p. 22-371:

That's what Acura is claiming. YMMV.

Gboyz78

Hey guys check this out too.. Upon getting into the main navi screen (MENU, MAP/GUIDE and CANCEL).. Press MENU for 2-3 seconds and you can access the menu for changing the map and display colors and volumes. I can't remember all the stuff that you can do, but try it out. Last night, I changed the night time color of the map, it used to be black, now it is bluish green. Pretty cool stuff!

Ozzman

Is there a way to turn the navigation system off, similiar to how it goes black if you don't touch anything on it for a few minutes? Sometimes I just adjust the AC and then would like to get it back to the off screen, especially at night. I find myself looking at it when I should be focusing on the road.

larchmont

Sure, Ozz -- Hit the "Set-Up" button; then, on the screen, press "Display - Off."

Ozzman

I guess I should have been able to figure that out. Once again Larch, you da man.

larchmont

Actually I didn't think it was that easy. I found it out only through persistence (which probably doesn't surprise you).

Bear Trap

If I remember correctly, you can also use the voice recognition command "Display Off" to turn off the nav display.

Is anyone concerned about the NAVI touch screen getting dirty/damaged by repeated finger touch?

What's best to clean it with? 303 ?

Is there a protective skin that can be purchased to protect?

mg7726

asulak01: damp cloth is fine.

jlukja

Holy resurrected thread Batman. I read through the posts till I got to Larchmont's and I had to do a double take. A noob did a search. Good job noob, rep points for you.

accsuperstar

oh wow larchmount haha

Stevestr

a) Touch carefully with the tips of your fingers and not the nails. Keep the nails short.

b) Don't clean it with 303. I would think that would eat the protective finish off the screen. All you really have to do is go to an office supply store (Office Max, etc.) and purchase a 3M Dusting Cloth. Its a microfibre cloth that cleans the screen really nice. If the screen is really dirty use a bit of water on the cloth, not the screen.

I have been using this method over a year with no problems yet.

pcaulfie

Great info! Thanks!

I've got a mysterious scratch and would recommend a clear screen protector.

TSXChef

I also recommend using 3M Microfiber towels it works really well. I purchased a small eye-glass wipe version from Wal-mart store. Go to eye-glass section and look for small Microfiber wipe, they are about $2 or $3 and about 5" x 4" in size, perfect for glove compartment.

dnl2ba

Why, what happened to larch? I drop in now and then, but I wouldn't call myself a regular.

TSXChef

I don't think "Display Off" is a command, or lady behind my Nav doesn't like my Fabio accent.
Can anyone confirm this? thanks!

biker

Larch is/was the TSX man (well, PW really) until a few heated arguments made him leave. Other than a few folks on certain days without a doubt he posted more than anyone else. It's unlikely to find many threads before he left without some input from Larch.

And yeah, rep points for the noob for doing a search.

Whiskers

Not having to change the clock on Daylight Savings Time, priceless...

A-Q-R

I am using a cut out tranparency since day 1.....

Volzie

Can Anyone tell me how to adjust the display on the navigation screen so that it displays XM and CDs? I accidentally stumbled onto this setting but don't kow how I did it?

SupaRookie

This thread is 3 yrs old. You may want to post in the other section to get an answer.
