Anyone retro fitted carminat sat nav?

Quite like the idea of installing sat nav, but don't want a separate screen and wires all over the place. I've got a Vel Satis and couldn't find one with Sat Nav when I bought it. Has anyone retro fitted the OE sat nav?

Retro Fit

It can be done in a VW but its not so integrated as in a Renault. You would need a different screen for the display, the navi unit that sits in the dash, the NAvi disk reader and then a GPS reciever. Add to this the gyroscope unit and then wire into the original wiring to get the speed pulse from the road wheels , and the speaker unit for the navi ouput commands. To be honest its such an integrated thing in a Renault, I would sell your current car and buy another with it already fitted.

What's the stereo system like in the Vel Satis? Could it be neatly replaced with a standard DIN-E unit?

If so, then I'd be inclined to look at an after-fit system that replaces the stereo - preferably one with a retracting screen. With the screen stowed, the interior will look fine, and it won't look so bad with the screen out either (certainly no wires all over the place.)

Above all, don't waste money on the original CD based (rather than the later DVD based) Carminat. The system is dated, slow to recalculate your route if you miss a turn and has an interface that can only be described as 'user hostile.' You don't even get the 3D 'bird eye' view that all but the very cheapest after-fit models have these days.

If you really want the factory look (or something close to it) I'd look at getting the original navigation binnacle but putting something else inside it. I'll bet a TomTom GO or One would fit quite nicely in there, though the screen would be a bit smaller so you'd have to fabricate some sort of surround. In every other respect bar the screen, this system would knock the spots off Carminat, and I'm sure it would work out a whole lot cheaper too.

Horatio, the factory fit stereo is outstanding, the Renault phone kit hooks into the radio and it's a bigger than DIN aperture, so I don't fancy swapping it. It's a 2004 car, so I assume factory original would be the latest Carminat - but thanks for the watch out on the CD based system.

Mushroom - yep, that's all the stuff I'd anticipate having to get fitted. It's a 2.2 Privelege, 04/54, but like I say, I couldn't find a newish one with sat nav when I bought the car last October. 9000 miles later I'm still happy with the car, but don't want to swap yet.

It could be poss, but there are a number of things to consider.
If its a 2004, then you should still be under dealer warranty, this will defiantly end that.
Anyway how the carminat works. Basically a VDO Dayton on steroids.
It comprises of two units, the CCU (renault bit) and the carminat computer(VDO bit).
THE CCU (Central Communication Unit) connects to;
The vehicles multiplex network. (everything talking to everything, eg ABS, ECU , Xenons etc) ie. The CCU uses the ABS computer for speed.
Radio, for display overlay.
Voice Synth con,
steering wheel radio control,
ext temp sensor,
plus many more.

So you need to wire to all this!

To install the screen on a vel satis means removing the dashboard, and will mean removing the steering wheel, which means dis-arming and removing the airbag. I for one would not do this, airbags can save you, but if you are unsure of their safe removal, they can also kill you.

Problem is your model will poss not have the correct wiring loom. It will mean some serious wiring and messing about with scotch-locks.
I'm not sure where you can connect to the multiplex network, but a word of caution. The Multiplex network allows devices to talk. eg the ECU sends out revs, the dashboard receives this info, and displays it on the dial. The multiplex network is a twisted pair bus network, which requires terminating to function. (kind of like ethernet, for IT people) This is done by the ECU and UCH . If you hack this about, then everything could stop functioning. Immobilise, door locks,ABS, etc (If you want more on this, best to search on the WEB for the CAN (Controller Area Network) protocol. This is an open standard that most car manufactures use, inc renault).

Not to put you off, but I will be surprised if any dealer will do this. If they did, the labour hours would be massive.

I personally prefer, same as you, the built in ones compared to the cheap stick on windscreen jobs. The nearest you can get to go for something like the VDO Dayton, with and Ext 5" screen. Plus add-ons like, reverse camera, TV, TMC,

If you are like me, then I like it to look neat, and I do not drill holes in my dash, checkout. They do have an english site. I have not used them, but I'm looking to order one for my carphone.

As it a lot of hassle, I just bought my car with it fitted.

If you want more info then post a reply, and will try and answer.
