ECM Engine Control Module Typically referred to as the ECM
FAQ Frequently Asked Questions 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 The GA-Net allows the audio unit to communicate with all the audio and navigation components in a vehicle If there is an open in the GA-Net, components or the entire audio and navigation system may appear inoperative
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
HDD Hard disc drive The navigation does not use a DVD, but uses a hard drive to contain the navigation software Can be updated with a CD or DVD that is inserted into the audio disc slot
HDS Honda Diagnostic System A hand held tablet PC used for in diagnosing vehicle problems This device can be used to obtain DTC codes for diagnosis of the navigation system and CAN related problems
HIP (AcuraLink) This device receives information from the XM satellites and passes XM audio information to the audio unit In addition, traffic and weather information is sent to the navigation unit
HFL HandsFreeLink uses Bluetooth technology as a wireless link between it and an approved Bluetooth compatible cell phone See the vehicle Owner's manual or Quick Start Guide for more information
HFT Hands Free Telephone - see HFL
H/U Head Unit The navigation system display 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
Interface Dial This control device consists of a rotating knob and the buttons surrounding it This device allows control of the navigation, audio, and climate functions displayed on the screen
Jog Dial See interface dial
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 displays the current street name in the bottom-shaded area
Mated The process where the audio-navigation unit electronically writes its passcode to the HDD
Mic Abbreviation for the microphone used for receiving voice commands The ANC unit may also use it to check its tuning (if equipped) It is located near the map light in the ceiling
MID Multi-Information Display

MW Maneuver Window While on-route to a destination, this window displays information about the next maneuver
Navi Abbreviation for the Navigation System
Off-Road Tracking See Breadcrumbs
Off Route This occurs when the user leaves mapped roads Off road tracking dots (breadcrumbs) are displayed if the option is enabled in the setup menu The user can use them to return to a mapped road The bottom of the navigation screen displays "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 Make sure that the sliding door is closed at all items, if opened, an error message is displayed on the screen (if equipped)
