GLOSSARY REFERENCE
| Item | Definition |
|---|---|
| Address Book | The HFL system can import a copy of the phone book from and approved HFL compatible phone and can display the imported phone book on the navigation screen as the address book. See the Owner's Manual for more information. |
| Audio-HVAC subdisplay | The upper display that shows the time and current status of the audio and climate control systems. |
| Breadcrumbs (white dots) | Off road tracking dots that can be followed on the map to retrace your route back to a mapped (digitized) road. This function can be turned on/off in Setup screen 1. |
| CAN | Controller Area Network. This communication network allows processors in the vehicle to send/receive information. The fuel pulses used by the trip computer are received from the ECM/PCM using the F-CAN (Fast Controller Area Network) bus. |
| B-CAN | Body CAN Bus (see CAN) |
| CPU | Central Processing Unit. The main device within the navigation unit that coordinates the rest of the electronic functions. |
| CSS | Countershaft (Output) Speed Sensor. This sensor reads the output shaft speed at the transmission and provides a speed pulse to the ECM/PCM. |
| Database | This consists of the Map data, and the POI (Points Of Interest) data stored on the DVD |
| DBW | Drive By Wire. Allows electrical control of the throttle without the need of a mechanical linkage. |
| DCA | Detailed Coverage Area. Main metropolitan areas in the Lower 48 states, and Southern Canada are mapped to this level. See the navigation system manual for a list of these areas. |
| DTC | Diagnostic Trouble Codes. Use the Honda PGM Tester, or HDS tablet to obtain, and troubleshoot the cause of these codes. |
| Dead Reckoning | The use of the speed signal, and yaw rate sensor to position the vehicle on the map even when tall buildings, or driving in a tunnel obscures the GPS signal. |
| Digitized Road | A road that appears on the navigation screen. The road name will appear at the bottom of the navigation screen. If the user drives "off road", the navigation system will display "Not on a digitized road", and if 1/2 mile, then "breadcrumbs" will appear. |
| Disclaimer Screen | Screen containing cautionary information. It is meant to be read carefully and acknowledged by the customer when using the navigation system. |
| DVD or DVD-ROM | Digital Versatile Disk. The navigation program and database resides on this disk. See the Navigation Owner's Manual for information on how to order a replacement or an update DVD. |
| ECM | Engine Control Module. Typically referred to as the ECM. |
| E/T | Elapsed Time for the current trip as displayed by the trip computer screen. |
| FAQ | Frequently Asked Question. See the Navigation Owner's Manual for a list of the customer FAQs, and troubleshooting information. |
| F-CAN | Fast CAN Bus (see CAN) |
| GA-Net bus | A data connection between the display panel, the navigation unit, and the audio system. The information passed on this bus are touch screen button commands, and audio and climate control settings directed by the navigation unit. |
| GPS | Global Positioning System. A network of 24 satellites in orbit around the earth. The navigation system can simultaneously receive signals from up to 12 satellites to accurately position the vehicle on the map. |
| HDS | Honda Diagnostic System. A hand held tablet PC used for diagnosing vehicle problems. This device can be used to obtain DTC codes for diagnosis of navigation system CAN related problems. |
| HFL | HandsFreeLink uses Bluetooth technology as a wireless link between it and a Bluetooth compatible cell phone. See the vehicle Owner's manual or Quick Start Guide for more information. |
| H/U | Head Unit. The navigation system display unit assembly in the dash. |
| Initialization | This refers to the period needed to re-acquire the GPS satellite orbital information whenever the navigation system power has been disconnected. This can take from 10 to 45 minutes. |
| LCD | Liquid Crystal Display (the navigation screen) |
| Map Matching | The received GPS information allows the navigation system to position the vehicle on the map. Map matching has occurred if the map screen is displaying the current street name in the bottom-shaded area. |
| Mic | Abbreviation for the microphone used for receiving voice commands. It is located near the map light in the ceiling. |
| MID | Multi-Information Display |
| Model (in the diagnosis Version screen) | A "model code" stored on an internal "chip" in the navigation unit. The model code tells the navigation unit what software to load. Every navigation unit "model" has a unique part number for the navigation unit. |
| MW | Maneuver Window. While on-route to a destination, this window displays information about the next maneuver. |
| Navi | Abbreviation for the Navigation System |
| Off Route | This occurs when the user leaves mapped roads. Off road tracking dots ("breadcrumbs") are displayed if the option is enabled in Setup. The user can use them to return to a mapped road. The bottom of the navigation screen will say "Not on a digitized road". |
| Outlying Areas | These are rural areas that typically have only their main roads mapped. All other roads are shown in light brown for reference only, since they have not been verified. |
| Paired | Linking your cell phone to the HFL |
| PC Card Slot | The PC Card (PCMCIA, type II) slot is for factory use only. |
| PCM | Powertrain Control Module. This unit supplies the navigation system speed signal, and sends fuel pulses for the trip computer function via the F-CAN network. |
| PCMCIA | A computer industry defined term referring to the PC Card slot standard. |
| PIN | Personal Identification Number. A random 4 digit number created by the customer to protect personal information. |
| POI | Point Of Interest. These are the businesses, schools etc. found under the "places" option on the main menu. |
| Polygon | Colored areas on the map screen denoting parks, schools etc. See the Navigation Owner's Manual "Traveling to Your Destination" for a list of the assigned colors. |
| QWERTY | Keyboard layout resembling the typewriter keys. The keyboard layout can be changed to an alphabetical layout in the Setup mode. |
| SCS service connector | The 2-pin connector used to put the navigation system into the diagnostic mode. |
| Security Code | Code needed to activate the navigation system. You can obtain the security code from the "iN" (interactive Network) by entering the navigation system control serial number. You can find the serial number on the diagnostic screens (Unit Check, Navi ECU), or on the underside of the navigation unit. |
| Touch Switches or Touch Sensor | The navigation screen is covered by a clear film that has 1 vertical resistor and 1 horizontal resistor. When the user pushes on the screen, the voltage is read across the resistors and the desired function is selected. |
| Tuning | A continual update of internal navigation system scaling factors. See the individual sensor tuning discussions under either "System Description", or SYSTEM DIAGNOSTIC MODE . |
| Unverified Streets | These streets have not been verified for turn restrictions, one-way, etc. They are shown in light brown on the map. You can enter address destinations in these areas, but voice guidance ends at the last verified street closest to your destination. |
| Off-Road Tracking | See Breadcrumbs |
| Verified Streets | These streets consist of the detailed metropolitan coverage areas, and all other inter-town connection roads. These roads are shown in black on the map. |
| VP | Vehicle Position. When in map mode, this circular icon shows the vehicle position on the map. Touch this icon to show the latitude, longitude, and elevation of your current position. |
| VR | Voice Recognition. This allows voice control of many of the navigation functions. The hardware consists of the microphone, steering wheel (Talk/Back) buttons, and the front speakers. See the overview for more information. |
| VSP | Vehicle Speed Pulse. This pulse signal conning from the PCM is used to update the Vehicle position on the map, and to calculate the trip computer fuel economy. These pulses do not indicate direction (forward or backward). When in reverse, the navigation receives a signal from the MICU and directs the VP to move backwards on the map. |
| VSS | Vehicle Speed Sensor. This sensor reads the output shaft speed at the transmission and, provides a speed pulse to the PCM. The PCM sends this pulse to the navigation system and speedometer. |
| XM Satellite Radio | A satellite band radio system where signals are received from either a satellite or land based transmitters. |
| Yaw Sensor | This device is located in the navigation unit and senses the side-to-side twisting force generated when the vehicle turns. |
