So this little lot turned up today.

But just looking for some advice having never fitted one of these before. Will it be the case of pulling out the stereo, disconnecting the wires and then hooking the existing ones to the new unit, including the stalk unit & stalk patch lead, microphone etc...
 
What sort of car?

Looking at the adaptor, it's a quadlock canbus which often doesn't provide a switched live - so the stereo will stay on all the time. You normally have to run a switched live from elsewhere to do that but it's car dependent.
 
Should have gone to Halfords, I hear they fit if you buy it from them.

It used to be in the old days whip out the old one and simply slide in a new one.

Newer cars have different setups.

Does it have DAB ?
Bet it ain't too long before the analogue signal is turned off.

It's a Ford C-Max 59 plate.

Sounds like I'll need to make some additional changes in regards to the quadlock?
 
My BMW has a quadlock connector and the problem was that it doesn't provide a permanent live so I had to run a wire (provided on the harness) to the battery. More of a pain because the battery is in the boot so I had to lift trim up and run it all the way through the car. The switched live was fine though in that when the permanent live was run, the new head unit fired up and turned off with the ignition as it should.

However, you should be fine with a C-Max. I fitted a new stereo to my wife's S-Max which is also a 59 plate and the quadlock harness I got just worked with no messing around. The stereo comes on when the ignition comes on as you'd expect and the settings are saved so the permanent live is also fine. If it needed extra wires running, the harness you've got will have them present so you'll soon know - the harness I got is listed as being for a C-Max too so I'm pretty confident it'll just plug in and work for you. The extra 3 wires you've got on your harness will be for reverse sense (used if you're using a head unit with reverse camera input so it can auto switch), handbrake signal (for head units that can display video so it can stop displaying video with the handbrake off) and speed pulse (for head units with satnav so it can keep tabs on speed more accurately).

Steering controls just worked straight away with no messing around too. Harness had a connector to plug into the little black box for dealing with wheel controls and the patch lead plugged into that then into the head unit, straightforward stuff. It should literally be a case of just plugging everything in and it should work :)

Excellent, cheers for that.
 
So I was really surprised on how easy it was to fit the new stereo. But I had real issues with the fascia and need to sort it out tomorrow. Not happy that the Bluetooth mic is poking out the front of the unit either.

But well pleased I decided not to shell out for someone else to fit it.

On the S-Max for the head unit mic I fitted, I managed to thread the wire in between the steering column and the dash dials. I just unlocked the adjustable height wheel it and moved it down as far as I could then poked the wire through. Eventually managed to pull it through from behind the head unit. Just pulled all the wire through then clipped it on the plastic so it sits just by the dials. Depends where you want it of course but it was the neatest solution I could come up with without having to remove bits of trim etc. I imagine the same approach would work on a C-Max too.
 
In a couple of cars now I've managed to run the mic cable left in to the glovebox, out the bottom by the door and up to the dash, round the front edge of the dash at the bottom of the window and then up the A pillar tucked behind rubber trim. Neither of the cars were a CMAX however so no idea how helpful that is.

How much? There are no plans to switch off analogue signals. They were going to do it in 2018 but those plans were shelved ages ago. DAB has been around in the UK for over 15 years.
 
People will come round to my way of thinking and start using Internet radio more than DAB before anything happens to FM

I travel all over the UK and there are still large areas with no DAB or mobile data, FM is all you can get :(

Of course, but I personally find today that mobile data is more reliable than DAB. But moreso, look at the increased prevalence of smartphones over the last 10 years compared to the uptake of DAB. The only real barrier these days is data allowance, but again look at where we are today - generous or unlimited mobile data plans are not uncommon, compared to where we were even only a few years ago.

Plus look at how many people already have smartphones in their pocket and already embrace streaming - I just cant see a compelling use case for DAB. Car stereos are getting smarter with stuff like Carplay and Android Auto..... I'm pretty confident that by the time FM goes away, more people will have adopted streaming than DAB
 
Hated fitting the Kenwood in my astra mk5. Needed all different types of connectors which all come to around £50. Even now I still can't get AM radio, not sure which wire I missed.

Cheers for this, have taken a look and there is enough room to go behind the steering column and around to the back of the unit. I'm sure I have some soldering wire I can use to feed it through.

Nice, good job, it's not so hard is it? :)

Cheers, just a confidence thing having never touched anything on the car like that before. But really glad I listened to everyone on here :)
