AVENSIS REPAIR MANUAL (RM1018E)
PRE±CHECK
1. USER TROUBLES UNDER NORMAL CONDITION OF THE NAVIGATION SYSTEM
(a) Voice guidance does not perform in the following situation even if the system is in normal condition.
(1) The destination is not set up.
(2) The vehicle is not driving on the set route. (The remaining distance is not displayed at the lower
left of the map screen that tells the current position of the vehicle.)
(3) ºGuidance in Other Modesº is not set up. (In this case no voice guidance is given except on the
map screen.)
(b) The vehicle icon or map turns around arbitrarily on the screen even when the system is in normal condi-
tion.
If the ignition switch is turned to ºACCº or ºONº while the vehicle is turning around such as being on a turnta-
ble, the Navigation System memorizes the angle speed of that moment as the standard figure. To solve this
problem, at the vehicle speed of 0 MPH (0 km/h), turn off the ignition switch, and then turn it to ºACCº or ºONº
again to see whether any trouble occurs again.
2. INSPECTION OF THE LOCATION WITH TROUBLE OCCURRENCE
(a) Check whether the wrong display of the vehicle icon appears in a certain location or in several loca-
tions.
HINT:
It is difficult to determine the accurate vehicle position when driving on a freeway, a looped road or a road
which runs in parallel with another, and immediately after going out of the parking area. In such cases the
vehicle icon can be displayed off the real position of the vehicle.
3. OUTLINE OF AVC±LAN
(a) Each unit of the navigation system connected with AVC±LAN (communication bus) transmits a signal
of each switch. When +B or GND shorts out in this AVC±LAN, the navigation system will not function
normally as the communication is discontinued. In this AVC±LAN, the multi±display (CRT display) dis-
play becomes the master of the communication, and resistance necessary for transmitting the signals
is stored in the radio receiver assy.

PRECAUTION
1. OBSERVE HANDLING AND OPERATIONAL PRECAUTIONS
(a) Please explain to the customer that when the negative terminal is disconnected from the battery, the
channel information memory of the AM/FM broadcast stations in the radio receiver is cleared. If neces-
sary, make a note of the recorded channel information before the negative terminal is disconnected,
then reset the information after the negative terminal is reconnected.
(b) The removal/installation of the radio receiver should be performed after all the cassette tapes and au-
dio CDs are ejected from the radio receiver.
HINT:
If the cassette tapes and the audio CDs cannot be ejected due to the malfunction of the radio receiver, do
not try to drag them out by force. Bring the vehicle to the repair plant.
(c) Fasten the earth bolt securely when the antenna cord is removed or installed.
HINT:
Failing to fasten the earth bolt securely causes noise at the time of radio wave reception.
(d) Do not touch the cone paper of the speaker.
