When my dealer replaced my Nav system under warranty, he forgot to program it for the stock wheels on my car, and I had the same problem with a COMAND 2.5 unit. This is different from the tire size programming that you can do in the COMAND "Navi Settings - Calibration" menu.

Since you have entered your proper tire size, and whether they are new or used, into COMAND, and it didn't solve the problem, the dealer will have to do the rest.

Incidentally, if you don't have a COMAND user manual, Paul Dick has posted them at http://home.earthlink.net/~phdwebsite/comand_manual.htm

Firmware can be a problem; the firmware update discs are listed as tools (not parts) and are made available to the service department. Dealer "parts" departments will likely not have a clue. Try contacting your dealer's telematics tech, and see if he can order one for you. Also, listen to any cautions he gives you about "Flash updates" (firmware updates). If he is cautious, he may not be able to help you out of a bind if the update wasn't correct for your COMAND or car.

You don't say whether your COMAND is U.S. or European - there is a download for European COMAND updates somewhere on the Web - you'll have to search the forums for it. However, it won't work for U.S. COMAND systems, and the same cautionary advice applies from the preceding paragraph.

 

Thanks for the info. My command is the euro version. The reset you speak of, is this the reset done in diagnostic mode? Is it as simple as clicking on reset or is there other information that needs to be entered? Thanks.

Not a "reset;" the "rest." Dealer has to do this through the STAR diagnostics computer (a laptop with proprietary M-B software). Mine charges about $95 just to hook it up and do anything simple. More extensive diagnosis costs more.

 

Ok, thanks. One last question. I found the download for the command update. I read someone saying hold down the * & # while powering up. This shows me i have the 99 version and the 2002 version is in the cd rom, says preparing to download cd, and the screen goes black. Any ideas, or directions on doing this update. Thanks

 

Afraid I don't. Suggest you PM either Scorchie, MBenzNL (Steve) or Miroj.

 

Try this. Park near, or better in, an intersection the mapping software knows. Turn on the COMAND and push the NAV button. Use the right rotary knob to highlight SETTINGS. Press the knob. Use the knob to highlight LOCATION, and press the knob. Now enter the city and intersection just as you would a new destination. You can use the knob to tell the COMAND how far from the intersection you are by turing it. Press knob. When you see "Selected location being accepted" press and hold the knob until you hear the beep.

 

I'll try it, thanks.

 

Lynn, do you have any ideas about this problem?

My NAVI (04 CLK 500) works fine, except for the ETA. Since new, the ETA has been consistently off on longer distances. If I have 60 miles to go, and I am going 60 MPH (and I have been going this speed more than long enough for the NAVI to average it), the ETA will say it will take 1 hr. 20 mins. The closer I get to the destination, the more the ETA catches up, so that it gets to 0 when it should. The dealership ran its computer tests and could find no faults.

Any thoughts?

 

tried it, it found me at the moment, but once i drove down the street and turned a few corners, it was off again...

Tob...I had the same problem, it seems that a few Comand units have as what was described to me as a bad "bootloader" and won't take the s/w upgrade. Do a search on the "other" MB forum (comand update), you'll find some more info.

Also, regarding the accuracy of your Comand...are you sure that the VSS wire is hooked up correctly?

Good luck

 

ETA inaccuracy

The software which computes the ETA is essentially identical to that which is used by randmcanally.com mapquest.com and others to compute travel times. The software makes assumptions of driving speeds, rest stops, stops for fuel, traffic conditions, etc. Many of us drive faster, encounter light traffic and stop less which makes the ETA inaccurate.

 

RE: ETA inaccuracy

Thank you, Lynn. I think what you're saying is that there is nothing wrong with my unit. It is, I guess, correctly incorrect, given the software that is being used. Thanks for the explanation, because the dealership has no idea.

 

Thanks for the info, I'll research it. As far as the VSS wire, I think i have it hooked up correctly. I was told it is a green/black wire on the floor panel (passenger side). When i removed the panel, there were two green/black wires to choose from. (before i hooked this wire up nothing worked) now it tracks me, but is always off by 1/2 block or so.

 

Thanks for everyones help! I purchased another unit today and everything is working great now. I was relying on the word of the person I purchased this unit from on eBay. He told me my unit had the latest firmware, he told me not to worry that it was off by a block or so, and he also told me that it was a standard thing for the illumination not to work when you turn the headlights on. I put my new unit in, and all of the problems went away. This guy advertised on eBay that the unit would work, and he would assist with installs. This was a total lie. This guy was nothing he appeared to be. Be worry of this guy, I’m sure he’s sold lots of units that work, but if you have a problem, or a unit that doesn’t work - don’t expect him to even try to fix it. I had to file a paypal complaint and leave him negative feedback for him to respond to me. Funny, now he wants me to ship the unit back for a refund, WOW! The seller is at http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=7976559148&sspagename=STRK%3AMEWA%3AIT His name is Sunil Patel. He has several Id’s he uses, but the one he’s advertising under right now is medical_bliss -- Watch out for him, don’t get screwed like I did.

 

Hello folks. THe navi unit that Tobias Williams received was a 210 unit which was a MBENZNL unit. I offered a refund or replacement but he simply did not want to send the unit back to me unless I send his money back first or either a replacement unit first. Can folks that know me here please respond to this harassment.

 

And I don't go by different aliases or names. IT's been the same always.

 

I can vouch for Sunil anyday. I purchased a Mercedes comand for my c230 coupe and i just installed it yesterday. His service was excellent. He was very helpful the whole way. He always answered in a reasonable amount of time. His feedback speaks for himself. I don't think he would try to cheat anyone. I will always keep him in mind for future purchases. I don't know why you could not just return your unit for another one with him? I am sure he would have traded it out for you.

 

Great to be on these forums too! They are awesome!!!

 

I second Sunman is an honest and knowlegable person on Benz mods.

This guy was nothing he appeared to be.

"This guy" is known all over the World for having one of the most modified C-Class sedans - work which he did himself and surpassed all factory options possible with innovations no person has tried before. Has been published in several magazines.

"This guy" has sent me things on my handshake and never let me down.

"This guy" is one of Steve's (MBENZNL) best customers and a good friend of his.

I on the other hand have no idea who you are having done several things like
- made a mess of funds on PayPal
- refused to send back the faulty item
- misreprsented the honourable name of an MD

And for what ? A few lousy parts and a sleazy quick fix which is disgraceful behaviour. I apologise in advance if I am wrong but I dont think that will be needed.

Ohio ..... its not a state of the USA, its a state of mind.

So you went into the engineering menu and brought up the information page showing your velocity and forward or reverse gear. Without this information you can not say that the VSS is working correctly.

How many satellites are you tracking ?

Give me a screenshot of this working and I will take all my angry words back.

If you dont know how to enter the engineering menu then you need to attempt this
- press FM radio
- hold MUTE + 1 + 3 for several seconds till the screen changes.

In there you will find a GPS + velocity screen where you can attempt to prove me wrong - which I am happily accepting of.

I bet you $1 that it comes down to tyre size calibration.

 

Miroj,

Even if his unit defective or working, I still offered a replacement unit or a refund. He wanted his money first or the unit first. I told him i would need a deposit if I would have to send another unit first. He would not agree. He then told me he purchased another unit for 600 dollars somewhere else and wanted to keep the install parts that I had sent to him and just send the unit back for a partial refund of 1300. I did not agree with this and wanted the entire unit back then with install parts. He told me I overcharged him for the whole ordeal in the first place. I must have held a gun to his head and forced him to buy it.... although I don't recall of such an incidence.

 

tobiaspw - 5/25/2005 6:25 PM

he told me not to worry that it was off by a block or so,

I told him to finish the whole install first and "lets take it from there. If it's still off a block or so then I will replace the unit" THis is when he wanted a replacement unit sent first. I simply cannot do this with someone with a feedback of 7. It's just not good business practice. I never told him that I would not help out. Mr. Williams simply does not have any patience and wants everything overnighted to him. I told him it would take a few days atleast. He did not want to wait.

 

I have nothing to prove. I am happy I have a working unit now and don’t have to hope someone I paid a total of $2045 responds. The proof is in the forum here. Look at how many questions I asked and look at the date. No response from Sunil at all. Once I filed a complaint, suddenly he has time to respond... If he responded there wouldn’t be any questions here from me, I would have already had the answer from him. For the guy who asked about tire size and vss... All I did was plug in the new unit and put in my same tire size and all is well. I'm really not looking for vindication from you anyhow. I just was sharing my experience with the good folks in this forum that provided great advice for my problems. I thank you all.
