Double Din Fitting???

[prtklmb]

Ok found it.

It would seem they have added switches (although it doesn't show where they are).

Here's is what the guide says.

SETTING THE DIPSWITCHES

Before installation, make sure that the dipswitches on the interface are set according to
the below information:
Set Dipswitch 1 to ‘On’ if installing a Pioneer aftermarket stereo, and ‘Off’ if installing a
Sony aftermarket stereo. If installing any other brand of stereo, Dipswitch 1 can be set to
any position

Set Dipswitch 2 to ‘On’ if installing the product into a vehicle with 2 Line Display, and ‘Off’
if installing into a vehicle with 4 Line Display
Dipswitches 3 & 4 have no functionality with this product and can be left in their default
positions

I've made in the bold the area you want to look, change the switch and the display should work.

Hi Rusty thanks. Yes, I had bought CTKVX04 connects fittings kits as was suggested by them but the manual was for CTKVX01. Don't know the exact difference between those two products but looks the same. 

The link below was the exact instruction that I had received.

I uploaded the images yesterday to show the dip switches and internal circuit board layout but don't know if you were able to see it (Is there an easier way to upload the images?).

I also tried the mentioned dip switches but found out that if dip switch 1 was off with 2 on - only volume controls would work from the steering wheels. if switch 2 was off with 1 on only volume would work but if both on all the functions would work in the steering wheel controls. With all this the display did not come on.
