Anyone replaced the satnav in their Sport/Disco 3?

I was going to buy a new (updated) nav disc, but then got thinking.

With a bit of thought you can get a gps double din infotainment thing from Ebay. A simple purchase of a wiring harness bridge allows the connection between this and the aux in on the existing head unit. Add in a USB input and suddenly for around £100/150 you have Google Maps/Waze/CoPilot and Spotify, etc. I reckon a reverse camera would be a simple add on.

I had a poke about today, and the only issue I can see is mounting the unit at the correct angle for the dash. The existing nav screen is built specifically for the angle, but it can't be beyond a bit of thought to mount the double din cage at the right angle.

Anyone done this?

What spec of car have you got? Harmon Kardon Logic7 Stereo? It ain't simple I'm affraid. You have two options. Both retain the main large info screen.

Option 1
Bin the standard stereo and amp and replace with double din of your choice. I recommend a Pioneer Apple CarPlay / Android Auto unit with DAB. You need a an amp bypass cable along with appropriate steering wheel controls adapter. Want to keep the sub? You need a single channel amp for the sub.

Option 2
Keep the amp and bin the head unit. You need a fibre interface kit which was about £280 but prices now seem to have creeped up to about £330. This retains full use of the amp. Replace head u it with Pioneer unit as above.

Both need a double facia adaptor. Budget about £1k for a drive in drive out service for option 2 and less for option 1.

Both are perfectly fine 🙂

Ahh, yes. I've done the research for the HK Logic 7.

I'm happy with the sound from the basic head unit. It's the satnav I want to replace. I've found plenty of head units with RCA left and right outputs. I've also found a plug and play bit of loom that bridges into the Aux in of the head unit. So, I figure I can keep the Logic 7, and use the replacement for the nav unit on the Aux button for sound input. Its fitting the unit in the gap where the factory nav has been that is the challenge.

At least I think that will work.

The Aux input is pretty poor and quiet when compared to normal CD and radio. Whilst this may not be what you want to hear, but the only two options are the ones I have mentioned.

They keep the satnav screen and there for the 4x4 info screen, but you can proper phone integration with Apple CarPlay and Android Auto.

Parrot MKi9200 is another option and you can get that with the KAM cable which connects directly into the amp. Parrot scren isn't very big, but it does the job better than the aux input options.

I moved my Disco 4 headunit to the upper glovebox (in order retain radio function and bluetooth connectivity) and put a Lenovo Tab 3 in the hole in the dash (kept the factory bezel).

Initially I plugged the Aux cable into the tablet and then the aux socket in the car for sound, but have since bought an LRBT-II rom America and now connect the tablet to the bluetooth. (My car was of an age where the bluetooth only supported phone, not audio streaming)

So I now have google maps, amazon music, waze and TV in the car. For the TV I just tether to my phone hotspot. Hardly ever use it mind, only once in the eurotunnel car park when we were delayed and her indoors wanted to watch Strictly.
