SOLVED:Lost Sat Nav, Phone & Radio:Told Amp Gone in 2015 LR4
Hi all
Control screen grayed out for some functions but 2nd screen showed it is in fact the amp that has gone.
It appears to be part no. LR059979 so looking for 2nd hand one (Replacement circa £900) but also anybody replaced this previously and know is it located below the driver seat or in the boot / trunk area ?
Local LR shop will likely have to fit / code but seeing if anybody else has replaced and how that went.
Cheers

I changed the amp in my Freelander and no coding was required. It is 15 year old technology so things may have moved on

Found this handy little video. As I feared looks like taking most of the trim apart front and back. Good to see this as well as the tech bulletin around troubleshooting the MOST ring being the way this should be tackled.

So I tested the DAB / Sat Nav for light emitting to carry along fibre optic cable as well as input cable carrying light. Both a yes.
Looked at the amp and no red light emitting then put simple meter onto the power input into amp as there is no way I could have 2 dead amps.... I don't....
Downloaded the full manual and wiring diagram to trace the power for the amp back to Fuse Link 11 in the engine compartment and it was blown. Used another from a less important system for now (will get new FL tomorrow) and everything pops back to life.
Seriously spitting feathers that supposed Land Rover specialist missed something so simple as did I.
Lesson learnt - now I have a spare High Line Display Unit and amp.... lol
I do though once again have a functioning Disco

Good work. Always the least expected fault! It's called 'black box syndrome'. People always think it's the black box because it's a mystery what happens inside!Richard

You should be asking 'why did the fuse blow?'. that will be the real diagnosis.
