It took me nearly 17,000 miles but I finally found out what that "Repeat" button under the telephone keypad on the PCM is for when you have the navigation system taking you somewhere. It repeats the last navigational instruction (audio) and updates it for distance appropriately. For example, if it told you to prepare to make a left turn at 200 yards press it again in a few seconds and it will tell you to prepare for a turn in 100 yards, etc.
Some of this stuff takes a long time to learn.
Any other navigational trivia facts?

So far I've figured out that if you press the "map" button a map comes up with a little triangle representing you.
Reading the manual, it seems that the nav system uses not just GPS but mechanical odometry to figure out where you are. So this can make it a step above a handheld system relying on GPS alone. Tres cool! I wonder if this is pretty standard across built-in nav systems available with most current cars.

In Europe in particular, some of their tunnels are substantial,--miles long. The car has the ability to DR,--dead reckon,--for substantial distances when the GPS signal is interrupted. When the signal returns it puts you right back on centerline.

I still don't know how to work that Nav on my car.... Sometimes on the map, the street name of the next turn will display on the top left corner of the screen, but sometimes, it won't.
I need to press the Nav button to see what is the street name of my next turn, and then press the Map button again to see the map, and then the Nav button, then the Map, .....
Why doesn't it always display the street name of the next turn on the map screeen, just like most other GPS system? It seems have its own mind to determine hidding the street name until I am almost approaching the turn...
With best regards,

I wonder if the nav system has a gyro built in to help pick out when you are turning, or if it just assumes you are staying on a road and computes how far down the road you've traveled. Modern cheap MEMS gyros can sense turning rates of around a degree per minute.

Thanks. I did read through the manuals but seemed couldn't find the setting (if any) to force-display 'street name of the next turn' on Map screen all the time...
So far I keep swtiching from Nav and Map screens, so I can see both the map and the street name of the next turn. It is a little frustrating when I am navigated through tight city street routes...

I saw this for the first time the other day (the street name at the top). I can't tell you why it does it sometimes and not.

Press right (not correct, rather the "not left") button. You can now choose "map cursor". Move the cursor with number pad, and zoom in/zoom out by making the rectangle smaller/bigger using the left button. Pick a point, and choose "route guidance".
Great for getting to twisty roads. I have used it in the following way... use google on PC to find a nice twisty mountainous road. Get in the car, and using map cursor, tell Nav to take me to a point on the road. Once there, enjoy the drive.

Anyone else ever hears the "Caution, restricted access" line? It happens at one of the hospitals I work at but nowhere else that I travel to. I get a kick out of it.
One other feature that I like relates to one of the Boston harbor tunnels that is part of the "Big Dig" here. I guess it was made after my NAV disc so when I go through that particular tunnel, my car is zipping across a blue screen of water.
