Operating instructions

(This will work both for the small and the wide Display)
Video can be seen on: http://www.nasab.com/Volvo/tip-trick.htm where we have put up some video
from our test and the last one which is a final working Standard Navigation in Volvo RTI unit.
(Final edition together with NAV Voice Guide over TV tuner)
First of all everything depends on how much you want to spend both in money and time (When we refer to
cost we do not consider NAV unit only the cost for some electronic parts, connectors and cables):
1. You can make the replacement very easy and cheap by just take out the RTI Display and replace
it mechanically with a TOMTOM, Garmin or Lark NAV which has 4.3 inch Display and use a
switch to operate the Up/Down and to turn the NAV On/Off. This is the simplest way of doing it.
2. You can use a sophisticated pc board with microprocessor to communicate with the can bus and
by then you would be able to operate the RTI Up/Down with the original keys on the steering
wheel or by the remote control. This is very complicated and difficult solutions and expensive and
you need to have know how, how to programming microprocessors and not very easy for the
common person to achieve. In this way you also have to mechanically replace the RTI display
with some kind of NAV.
Our Project
3. Our NAV have Dimensions: 295.6 x 204 x 7.95 millimeters and that is max what you can use in
Volvo with the small Display. (Measured outside the NAV). And remember feathers like back
camera, video etc. depends on what kind of NAV you buy.
This way you replace the RTI mechanically and use some of the feature which is original in
the RTI electronics. We will in detail show this method as we think it would be the most
suitable way of replace the Volvo RTI with some kind of NAV where almost everybody can
do it as long as they have some kind of mechanical and electronically knowledge and it do
not cost more than between 10 to 50 Euro in material. We choose this way where you do
not need any programming and still have some feathers which operate the RTI
Display/NAV Up/down starts the NAV automatically when the RTI goes “Up” and shuts
down the NAV when the RTI goes “Down”. You can also use the original bottoms on the
steering wheel or the remote control for sending the RTI Up/Down, but nothing else.
