2014 Defender 90 Puma 2.2 XS CSW Corris Grey

JVC Unit Replacement

The JVC headunit in my 2014 90SW has given up.

I have the factory-fitted sub, which complicates things, because I want it to carry on working.

Forgive me, I have searched and read threads until my head hurts, but I'm still not sure what I need to replace this JVC unit with something like a Blaupunkt.

I'll need a loom-converter lead, I assume, to convert the wiring to whatever brand of head unit I buy...

But then how do I make the sub work? RCA? Some units have 2 RCA out, some 1? Does the RCA on the new unit need to specifically be a sub out?

A JVC is not factory fit in a Puma, so the sun isn’t “tied” to the JVC.

Any head unit with “sub” RCA outputs (2x phono sockets) will be ok. The remote switch on output required should also be standard on all head units.

Thanks for the reply Martin. Apologies - it's an Alpine unit.

It's definitely factory-fit, the truck came with the 'upgraded sound' pack.

You make a loom for the factory-fit sub, would that be what I need in addition to the ISO convertor?

Ok, same applies though. Use the wiring from behind the old head unit (phono adapter loom), and a new adapter loom from 2012+ Defender to the new head unit.

You probably have to go 2012+ to ISO then use the ISO to head unit cable your new head unit comes with.

If you buy a new Alpine you can use the factory adapter loom to the head unit.
