OK Team, I've changed HK7 amp, Nav player, small sub amp, traffic master, TV unit & nokia unit all due to water ingress. Do any of these replacement units need cooded to the car? The MOST optical light is going around all the systems (selid light) I can now connect my phone but still no audio...

So! A wee update I've changed HK7 amp, Nav player, small sub amp, traffic master, TV unit & nokia unit all due to water ingress. The MOST optical light is going around all the systems, I can now connect my phone but still no audio, can select radio but still no audio, the CD & TV I can't even...

To start off with I only had the driver information on the screen. I was able to select the radio but I had no audio and I couldn't select CD or TV. I looked in the back LH corner, and found the nokia, HK7 & Traffic Master where all corroded with water damage. I've purchased replacements &...

Sorry to piggi back Guys, but I'm having a similar issue with my entertainment system my post is here (https://www.landyzone.co.uk/posts/5428043/) was thus issue resolved? Any assistance would be greatly appreciated

I was having a look at a TV Unit and came across this https://parts.jaguarlandroverclassic.com/xra500052-tuner-television.html I presume there isn't much difference between the units?

TBH, I never even checked the V from the new battery, I presume it would have been correct I'll check again with a meter after it's sitting for the night. Took the dash off at the weekend too, to get at the unit behind the screen, em vents are a bugger to get out... lol That seemed OK too...

MF31 Battery installed, still no audio, nor select CD or TV. Going through test screens everything seems OK. The only unit I've not changes it the TV unit & Traffic Master unit. Would anyone be able to decipher the 2nd screenshot for me, does this screen tell me what's wrong.. lol No idea what...

Appreciate Bud, gonna have a bash tomorrow, will keep you updated. Don't even think that's the way it was set up before I ripped it all out. Will get the original battery back in it, on the build sheet it says 110Ah/850 Or should I put in the more popular 120Ah/1000?

Would a low battery cause no audio tho? I'll was only thinking it was low cause I was using the system without engine on. I'll look I to getting it replaced this wkend too. Would you know the correct battery it's the below one that in it

I would say I went down the wrong rabbit hole, the parts I replaced had corrosion on the motherboards. I've not checked the unit behind the screen yet, going to do that at the weekend. I started with only the car information & mpg on screen. And just a solid tone when I put it into reverse...

I have disconnected them in turn, check that when the optical it comes back out to other unit. So far it's only cost me £120 to replace the units. Is there a wright and wrong way to connect the optical cable. I did use a circuit diagram from rave. Would a replacement HK7 unit need coded

So a wee update, replaced my HK7 amp, DVD NAV player & Traffic Master. I now have maps working, still can't select CD or TV or have any audio. I suppose my next step would be the IHU behind the touchscreen, gonna have a look at taking the Multichanger out the glovebox tomorrow. Would anyone...

would anyone have a wiring connection diagram for the optical cable? in what order they would be connected?

Didn't know bout the diagnostics on the head unit. There are a few,

Yea, even opened the units up to have a look

Hi Guys, Im now to RR's and 4x4, I've recently bought a 2005 RRV, unfortunately when I bought it I didn't test the cd/radio, sat nav or TV and found out I have no audio, or parking sensors. I've tested the parking sensors (listened for the click) only 1 was quiet, but when I swap that 1 to...
