TEST MODE

Preparation: Connect the DVD Navigation system to TV monitor type of the KENWOOD touch panel.

1. How to enter the TEST mode.

(1) Touch upon the “Menu” on the TV monitor and switch to

the Navigation Menu screen.

(2) Touch the Area 1 and 2 on the Navigation menu screen in

the following order : 1 → 2 → 1 → 2 → 1 → 2.

(3) Switching the screen display on the Diagnosis Menu.

2. How to exit from TEST mode.

Reset the Navigation system by pressing the reset button on the front panel

3. Items on the TEST mode.

By doing the following, various information can be obtained from the Diagnosis Menu.

3-1 GPS information

The GPS reception status can be confirmed by touching on the “GPS Information”. When confirming on the GPS reception status, put up the GPS antenna at a location where nothing blocks GPS reception. If the almanac data is lost due to conducting repair work and the like, the data can be rewritten by receiving GPS information with the GPS antenna, while the vehicle is stationary for about 20 minutes. (1) Elv./Azm : Displays current position of GPS in elevation

and azimuthally projected direction.

(2) Level : The reception level from each satellite is displayed

in values (C/N).

(3) Status : Displa ys whether receiving or in use. When in use,

it is used for measurements. (4) Measurement Status : Displays - -/NG/2D/3D. (5) Date : Displays current time and date. (6) Position : Displays longitude and latitude of the current

position.

3-2 Vehic le Sensors

By touching the “Vehicle Signal”, the vehicle and gyro signals can be confirmed.

• Vehicle Section (1) Battery : On/Off. (2) REV : Turned on when the gear is in Reverse. (3) Number of SPD pulses : Indicated the number of ve-

hicle speed pulses. (Speed is indicated in two ways.)

• Gyro Section The following values in (1) and (2) belo w are changed when the ECU is rotated.

(1) Voltage : Displays the current gyro voltage. (2) Relative direction : Displays the current relative direction.

3-3 Color bar Check

By touching the “Color bar check”, RGB condition of monitor can be confirmed. Whether set color matches the display color or not can be confirmed.

3-4 Parts information

By touching the “Parts Information”, current NAVI and Disc information can be confirmed.

• NAVI Information Current navigation software and ROM used can be confirmed.

• Disc Information Current format and data versions can be confirmed.

3-5 SRAM clear

Touch the “SRAM clear” more than 5 second on the display when you need clearer data for SRAM memory.
