So what is the right part # then of the 2 disc set? I see 2 different part #s listed in these threads (would rather order it from the dealer)

I don't know - I don't have a set in hand that I know works on my car.

However... if you are going to the dealer's parts counter, it is almost always better to give them the last 7 of your VIN and tell them what you need, and let them look up the part number. That way, if it isn't correct, it is their fault and they should take it back. If you just give them a part number, you'll probably get the "no refunds / exchanges on electrical or special order parts" routine if it isn't the right part.

Of course, this doesn't work for oddball parts they can't find, but for a common part like a map update, this should be the way to go.

I just got my new CCC unit on Monday (finally BMWNA,) along with the new Tele Atlas DVD-ROM disc's. Two disks, with the same part number, just divided by east coast & west coast (along with Canada and Mexico on the WC disc.)

The system would not read the disc immedately and required a 5 minute shutdown to reboot and "update" the system (as per the what the screen said to do.)

I see no change between what my older CCC (NavTeq) had/displayed compared to the Tele Atlas DVD/CCC.

I will update everyone if I see any significant change.

Standard when changing map discs

Here's how to check for changes:

1. New Streets
Drive to an area that was not mapped on the old NavTeq disc (tip: don't use the nav to get you there because the street won't exist on the nav)

And see if it is mapped on the new TeleAtlas disc

Tip: due to the size of the USA, I you may need a few tankfuls of gas and a few years of your time to verify the entire country :-)

2. Changes in Street Names
Look up a street where you know the street name was wrong and compare between discs

3. Changes in POIs
Look up a POI that you know was missing on the NavTeq disc and see if it exists on the TeleAtlas disc

I think if you're read this far you'll understand how dificult it can be to compare maps, without any way of checking the disc data content

Eg: if you live in New York City, how would you ever notice how many roads change in Texas, or Seattle, etc?

HOWEVER you can check POIs.
Compare POI file sizes.
When you see a difference, use my POI Extractor to extract all POIs from each disc to excel sheets. Then compare lists and see which map has the most POIs.
Whether the POIs are correct or not you can only determine by either contacting each POI or comparing with some other source. Although how would you know the other source is correct?
Look up POIs and compare

Where can I find this POI Extractor?
