Sat Nav Screen

[Baddad]

Can someone either point me to current post or answer. 2007 RRS SC. Has the sat nav with TV option. Decided to upgrade with a new head unit installed by a local fitter. Purchased cable loom and gave to installer. Had a Kenwood DMX 710 BTS unit installed along with reverse cam and the Kenwood front camcorder. Love the set up but have lost the top screen functionality as I thought it would after doing research.

So I am bored looking at the top screen just with the Land Rover logo. Is there anything someone has done with this top screen that is not too complicated (not really in the RR vocabulary). I have seen posts on UTube of video set ups but they involve adding aDVD player under seat etc. I would love to get the sat nav and TV back up and running if it is at all possible. TIA

Hi,
I am about to do similar. I have started collecting components to do job. But now first I have to fix a Fuel & Coolant leak on my new acquisition. Problem is you're Navigation and anything Infotainment, goes through the factory Radio/Head unit. This has both copper wire and fiber optic connections. The amplifier (Harmon Kardon) is also connected by fiber optics. All depends on what you're FITTER had done (he should have explained details to you).

Installing a New Head Unit, will require removal of old unit. Thus making everything on the Fiber Optic line (M.O.S.T) useless or non functional. Removing factory head unit, requires unplugging wires and unplugging Fiber Optics. You can install a Fiber Optic link, which will return some of the functions to the car. But you will have no Audio through the car's Amp. You can (instead of link) install a "RCA to Fiber Optic" converter, this will allow audio connection from you new Head Unit to go through factory amplifier (this is a "D" Class amplifier with optical input). Various suppliers of this part, but AVIN of the USA retail it for about US$100.-, where others approach $300.- This will only get sound back and complete the (MOST) fiber optic loop. This FIBER OPTIC allows transfer of Digital Audio and other Data.

At this point I do not know if all you're ancillary's will work? You may or may-not need another box, Its called a "GVIF" (Gigabyte Video Interface). This is a converter using copper wire only and made specifically for given brands of car. Where you're factory head unit plugged in, this will plug in the same location with extra connections. If correct unit, will allow control from you're touch screen of the car, certainly restore all functions and give extra Video inputs, etc.

There is another option, if you still have factory head unit. What looks like a Cd/Radio is actually comprised of 2 units screwed together. Bottom 1/2 is a 6 stack CD player with a Radio/CD face-plate attached. Top 1/2, which is a metal box with connections only (screwed onto top of CD part behind Face of Radio), is actually L-R own GVIF. This has an Audio input. The connections run to rear of Center Console at the rear behind a flap, this is you're AUX I/P. This box can be removed from factory head unit. It gives an AUX I/P, which you can connect you're New Head Unit to. If you have this part connected, it retains all the original connections, copper and fiber optics and everything will work on car as it was. But you must keep that part (in other words factory radio) selected to "AUX" input.

Either of the above mentioned methods is not easy and requires some understanding of Land Rovers MOST system and general electronics. A lot of Car Audio specialist do not understand what is fully going on or even aware of the complexity of the system. Land Rover, Toyota, Chevy and other use the MOST system in some of their cars. But components and implementation of systems may vary. Lot's of luck to any-one attempting to upgrade this system. It's complex and not cheep and would not advise anyone to attempt this unless competent or a suitably trained Electronics Engineer..

This is the kit that allows the original screen to remain with an aftermarket head unit
