Then onto my favourite bit, modifying and updating the interior.... I have modified quite a few cars now to take a double din unit, and do enjoy it....
This is the starting point, a bare centre console wood trim, for those that don't know it is made of aluminium then covered in wood and finally veneer
The original command unit is a two and a half din and fills three holes, I bought a cheap two din surround to help with the sizing
Cut out the console and trimmed the surround to fit
Glued the surround in place, I used hot glue as its good for this type of thing
Then cut some wood to give me an edge to work to as the console has a compound curve and the surround didn't.
Used glass fibre paste to build up the surround, the tape on the wood stops it sticking to it and makes it easier to remove.
Removed the wood
Then it's just a bit of bodywork to sort it out, a quick dose of filler
Then some high build primer,
Flatted off and then some satin black, it's not really necessary to paint it before wrapping but it helps to be able to check what it will look like when finished... The tricky bit is working out the best position and angle for the head unit so that it looks good but also doesn't give too many reflections on the screen when in use, I modified the original mount for the command unit and welded it to the mound for the head unit so it is very secure and the angle has worked out just as I hoped it would..
I installed a night vision rear view camera as well so all the boot had to come out for the wiring, also took the door trims and rear side trims out, the back seat and rear centre cubby box, not much left inside now!!!
Found a pin out for the 2.5 command head unit from 2000 but unfortunately mine was nothing like it, most of mine was controlled by can bus, no reverse feed, or even a lights on feed so had to do a fair bit of tracing and wiring to get the head unit to work, is now working as it should, dims at night, automatically switches to rear camera as you select reverse, stays on when you switch off until you open the door... It did claim to have built in can bus feeds for the steering wheel controls and I did try to use this but the difference in voltage on the can bus from the steering wheel buttons is very small and the unit couldn't cope, but not too worried, it's hardly a reach to turn the sound down!!!!
I've got a Kenwood 7" head unit in my Volvo that I use every day, it cost nearly £1000 a few years ago, as the Merc is a weekend toy I didn't want to spend loads so thought I'd get one of the cheap ones from China via eBay for the Merc, this was the one I got
Erisin ES1006GEN 7" HD 3G WiFi Car DVD player TV GPS iPod SD Color illumination | eBay
Not bad for £164.00 !!!! it has
HD Digital Touch Screen, Colour Illumination, Dual Zone, GPS Navigation, Real Clock, Change Background image and Icon Position at will, Analogue TV, Radio RDS, Bluetooth hands-free, A2DP Bluetooth, Front and Rear View Camera input, IPOD Audio Input and Control, Games, Calendar, Calculator, Compass, virtual 6 Disc, Wi-Fi & 3G Internet Ready, USB, SD
It all works very well, takes a smidge longer than the Kenwood at responding to buttons but the only thing I can really complain about is that it totally mutes the radio when giving driving instructions, then waits a second before the radio comes back on... the Kenwood just reduces the volume of the radio as it plays instruction... Oh and you can't leave a DVD in the machine all the time as it won't switch to radio unless you eject it... hardly an issue!!!!
It also arrived very well packed and turned up within three days via airmail from China....
It comes with a built in microphone but I fitted an external one in the place Mercedes fit the original, just behind the rear view mirror, the hands free works very well, made a few calls and the quality seems good even at speed.
I removed all the wood trim from the door cards and trim to fully wrap it, you get a much better job than leaving them in situ, the heat the interior can get to will slightly shrink the wrap and you will see an edge....
I've found the other secret is to use primer on edges and areas where you have to cut it to size exactly and can't wrap it round, most of the Merc switches are such a tight fit you have to cut the wrap on the surface and not wrap it round as the buttons then stick in the hole!!
The primer is water based and will come off with remover should you wish to revert to original, bit difficult in my case with the modified console...
You can see the primer on these pieces
Then it was just a case of wrapping that nasty REAL Wood with some FAKE Carbon fibre!!!??! I used 3M Di-Noc Carbon Fibre Vinyl Sheet, there are cheaper ones and also a lot of fake ones around, they are nowhere near as good as the real thing, it's worth the bit extra...
Not going to go into the process here as it's been done to death but if you decide to have a go then just be patient at first and learn how the stuff works...
Here are some after shots when it was all back together and I'm pleased to say it's all working just as it should and no squeaks or rattles from anywhere
Centre console, I also had a go at the oddments bin lid and the switch plate above it, they were covered in leather on mine, primered the whole thing and the wrap stuck like poo to a blanket and didn't pucker when heated to set the shape so I'm hopeing it will work long term, the chrome elements were removed before wrapping, then refitted to give that factory look
Some detail shots,
Gear knob looks good
These are the bits that were leather covered
That chrome bit in the ashtray is backlit so really wanted to keep it
Passenger side and the centre have the carbon running the same way, from the top to bottom running forward
Drivers side is the other way, keeps it looking neat...
Rear vent
Rear cubby box, wooden top slotted so it can retract, lots of cutting here...
Oh and one last thing the head unit has is twelve different backlight colours for the buttons, they are also mixable so you can get the exact shade to match the car.... bit difficult to photo but the colours are spot on to the naked eye.... and no I wasn't doing 53mph when I took this photo it was in display mode....
