installed navtool this past weekend for a backup camera, so it's still fresh in my memory

unplug the blue connect wire from navigation

from the navtool plug-in blue back to navigation brain - the other end of the wire plug into the brown connect on the edge of the board.

from the navtool plug-in factory blue back to female white - the other end of the wire plug into the brown connect on the center of the board.

from the main plug connect white wire with black heat shrink to reverse

from top of the harness connect red to accessory power and black to ground.

put the car in reverse, turn off PDC and camera image will appear on the screen

took me one hour to install NavTool

 

So, do you need to select the navigation screen to see this, or will it automatically switch to that display from the home or other displayed screen?

 

yes, you need to be in navigation mode

 

Thank you that will help a lot

 

you welcome

 

Still trying to get around it eh?

 

When you take the jag screen off, is it part of the head unit or is it a seperate screen? the reason I ask is because in the past I had a nissan pathfinder which has a seperate screen to the head unit and to the nav system. I made a harness that sat between the screen and the rest of the system and managed to get it to engage automatically... the video signals to the screens consist (generally) power live and ground, red, green and blue signals and horrizontal and vertical sync. (RGB HV). I was able to work out which was which with a multi meter for the power etc and by systematically disconnecting the wires. h and V were easy as the screen scrolls, the colours were pretty easy too as when only 1 is connected the screen goes that colour, if two are connected you get another colour (blue and green will produce yellow for example) simple stuff really... easier if you get the harness from a scrappie so your not messing with the one in the car but dependant on the screen in the xk...

 

Yep, nice to know they didn't beat Steve to it (although I guess he could have reverse engineered it!).
So, still waiting on Steve's controller!

 

It uses the existing screen in the head unit, but the interface is actually made to the navigation unit in the trunk.

 

and that interface KJ is referencing is Sony's GVIF technology.

 

as of today I have received an email from NavTool with a diagram to install the unit now to put it in and with thanks to all who sent help

 

Ian, would you please post them. I'd like to see the differences/ benefits of this unit over the GVIF unit.

 

was wondering I have a harness with 7 wires in it do you know how they hook up not showing in the download they sent from NAVTOOL i think its for the camera red,black, gray, orange,white ,yellow and green any pictures would really be great thanks Ian

Looks to be pretty much the same, a couple of pros and cons on both sides.

NavTool Pros - Fewer wires in the harness (no analog audio inputs could be a con), software configurable (maybe a con, in that you need to download their software)

NavTool Cons - Doesn't come with all the parts and cables (no selector switch), no instructions in the box

GVIF Pros - Came with instructions, dip switch configurable (may not be as flexible), lots of wires in the harness, comes with hardwired input selector switch, and remote control for tweaking

GVIF Cons - Older tech (no HDMI), lots of wires in the harness for analog audio inputs (for each video input)

 

I have actually had experiences with other boxes before NavTool went on sale, there is a huge difference. NavTool have features that other units don't even have

 

Was that with units that would work with our X150 cars?
Did that comparison include the GVIF that several on this forum are currently using?
If so, what features have you found to be of use that were not available elsewhere?

 

NavTool was the last unit i installed, It has HD quality HDMI input, in screen menus , 4 camera inputs, USB updates and most important it's made in USA

 

As of today I have been on the phone with NAVTOOL the unit they sent me never powered up worked with a person on the phone who said connect it directly to the battery and still no lights then they said it was the cables I used so I bought new ones for the download from their site but still no green light so I was told to send email to RMA@navtool .com and wait again for a return of product to them and they will check it out Im hoping this finally gets resolved but Im not confident so far

 

I got my NavTool to work perfect right out of the box
