Possible to Retro 09 Hard Drive Command?
although according to the cost for the list of OEM parts that was listed on this forum in the past was around $5300.I never said "needs".... please re-read my post again and try to understand it. I said some people have posted that the controls were awkward compared to cars who actually have the rotary knob, which makes sense since the new system was designed to have that knob in place. Can it function without it? Absolutely. Is it much more convenient with the knob? Many people think so. I never said it "needs" a knob or must have a knob or anything like that.

), the "rotary dial helps" but the buttons are okay. Another thing that's better is they put the screen up at eye level and not down below where you have to shift your view from the road. I realize that would have meant a re-design of the W211 dash which would have been obviously not possible. But at least they did elect to use the 2.5 in the 2009's so that was a good thing.I remember a lot of people saying the conversion was pricey and so elected not to go through with it. I think Mo is correct in his real world cost estimate.
One thing that helps not having the knob on the 2009 W211s is at least having a full VC system. You can use VC instead of stabbing at buttons while having to look down away from the road. I use VC a lot. But with the conversion, what about VC? It needs a stalk on the steering column to activate plus a mic. Can you have the full 2.5 VC system on an older car? That would add to the conversion cost, too. Or is there a work around? Without VC it means you've only got the buttons....

Current prices for the conversion is ~$4100 and is actually easy enough for someone with moderate skills to achieve themselves. By the time you off the old comand components you're out of pocket is even less (About $2000) and for that you get MUCH better Nav (Since it's address level and live Traffic updates) HD radio, DVD player and most importantly MUCH better amps (main and Sub amps) that make a HUGE difference in sound quality all while retaining stock appearance, operation and integration

My live traffic is only available as a Sirius XM service. I don't have to subscribe to sat radio but do have to have the service activated for the traffic portion.
btw, where is the linguatronic lever attached when doing an upgrade? Is it the same as the factory install? It seems to be part of the column.
Another thing I like about the 2.5 is that you can use it with the display totally off (and just use VC in combo with the steering buttons and the IC readout.) Not sure if that was possible with the earlier COMANDS (?) And then there's the DVD-A playback for higher bit rate music.
You need to remove anything on the most ring that is NOT NTG 2.5 (In other words EVERYTHING that is in the car stock. Radio, Audio Gateway (Amp/tuner unit in the trunk) CTEL module, SDAR module (If installed) Lignuatronic module (If installed), CD Changer, Ipod Interface (If installed) Nav Processor/DVD Drive (If installed) Bluetooth Phone interface (If installed) You replace all that with NTG 2.5 headunit (which has Nav, Linguatronic, Bluetooth and DVD Changer built in), Main Amp, Sub Amp, SDAR/HD Radio module, Media Interface (Ipod interface) and a Conversion wiring harness from Comandonline.co.uk
Install took me 8 hours going very slowly, if I did it again I can probably do it in 4 hours

Main Amp- Anyone have an estimated price? new/second hand market? part #?
Sub Amp- $179 - there is one on ebay now - 130617371323 for example Buy it now @ $200 with a warranty available
SDAR/HD Radio module- part number? estimated price?
Media Interface (Ipod interface) - Not sure exactly what this is.. there is an NTG 2.5 Multimedia interface on ebay from Japan item - 250884737947 for about $231? it gives 2 AV input, audio output, satellite nav gps
Conversion wiring harness from Comandonline.co.uk - Seems this is about $268 USD
Thats about $2100 so far with the missing information from second hand ebay parts..

I'd drop $1500 on a system that would replace our head units and integrate to our existing interfaces (dash, steering wheel, etc) in a HEARTBEAT....
...but I'm thinking that for a similar to OEM overhaul, it's more like $4K realistically?

$4K outlay then you can sell off your old components for about $2K.
It does require quite a bit of Star Programming and you have to know what your are doing in order to make it work
Now...navigating on the steering wheel suck unless you make playlists for the new stuff you have...
Nowhere near what you get in a Ford Focus now.

In this case I think all that was required other than the headunit was a new wire harness.
Also in this case I dont think you would NEED to rip everything out - but you could to sell. The reason being the new HU has everything integrated so the other parts are therefore no longer used.
SOmeone can maybe verify - but from searching around i believe this is the case. Now if you presently have older Nav unit then the info posted about would be correct.
I'd be very careful when dealing with cheap items like that.

I need to talk to some guys at work, most likely could build some really cool demos around this kind of stuff...

Incorrect info. You have to have the MOST ring (Fiber optics) in the car already since NTG 2.5 is MOST not DB2. Everything in my previous post has to done, all original non NTG 2.5 modules have to be removed from the optical ring since they are not compatible
