Some result of test:
For the past week we have been having this equipment installed in one of our Volvo V70 01 and the result
has been very good, no problem with the electronic the NAV has been working as it should and the
original bottoms on the steering wheel and the remote controller has been working fine, also the feature
where you are using the NAV and you are on the road and you stops for filling gasoline and you shuts
down the car, the RTI goes down smoothly and starts again when you start the car again. The result of
this modification is very good so far and we will have a look at how to connect the sound to voice guide
channel of the Volvo. The problem is there is no voice guide channel in the original RTI display connector
and we have to go all the way back to the TV module in the back of the car to find a connector which have
voice guide channel or to the radio module. Then you have the Melbus protocol to consider. But we will
see if we can go around this as we have done with the RTI unit already. Would be nice to get the voice
from the NAV to be sent over the voice guide channel or else we have to connect a separate speaker just
for NAV. But that is the last solution we will take, first we will try to go around the Melbus protocol.
Why we done this:
1. We were tired of Volvo who had not made any maps for Eastern Europe.
2. As we have a factory in Poland and we cannot get any maps at all for Eastern Europe CD version,
they have never made it, only for DVD RTI.
3. Maps for Western Europe inclusive Scandinavian not up to date and will never be.
4. Why have an RTI in a car you cannot use, better modify and use it.
5. And with this you can update the maps by USB and Internet.
The Audio NAV Voice Guide Sound modification to the TV tuner you can find on our web site:

We have made some more opportunity to connect NAV together with RTI as there has been some
question around this. Pls. see new drawings for +5V versions.
Also we has discovered the angle for NAV has to be adjusted with some rubber in the top due to it is hard
to read the NAV when the sun shines.
Make the Angel different.
The angel should be a little bit more backwards due to it is
hard to read the NAV when the Sun is shining.
Stripe of 2 or 3mm rubber along the top of the NAV will
make the display in a better angel.

Someone sent us an e-mail and told us “If you take out all CD
you just have to press ENTER for up and down of the RTI
module”, Thanks to this clever guy.
