Is there an easy way to tell

I don't think your window sticker will tell, unless that theory was true about the price change at the time the switch was made. A build sheet would probably have that info, and you can read it off of the sticker in the glove box. I am not aware of other ways to tell.

This is NOT true. Thanks to all who posted on this thread, I recorded two MP3 CD's, one with bit rate of 128 kbps and one with bit rate of 256 kbps. I put about 12 CD's in the 128 MP3 CD and about 6 CD's in the 256 kpbs. They both played fantastically on my Nav unit and I love the menu feature and the sound. I created albums with song lists, it is a lot of fun. I have a build date of 8/12/2005. I couldn't tell much difference between 256 and 128 but a friend says he can.

Both CDs gave the same incorrect CD message when I tried to play them. Also what does your glove box sticker indicate U3U or URB.

Having tortured Denso and GM customer service for nearly a year on the MP3 disaster with no results, I switched gears and called my local Chevy dealer yesterday. I asked if they would swap out the NAV unit if I complained enough about the static issue and the AVC (the auto volume thing) not working...they said yes. Now this doesn't guarantee I will get a replacement NAV with MP3 capability. I also mentioned the MP3 update and he said he would call the people he knows at GM to see what he could find out. Not holding my breath on this but you never know. He said I could schedule an appointment to bring the car in next week for a look.
My two questions today are...has the part number for the NAV unit changed from 2005 to 2006? If not, how can you tell if a unit will read MP3's without installing it first?
If you have had a 2005 NAV replaced under warranty has the new unit been MP3 cabable? I want to figure out if all the "old style" units are out of stock!

Okay.. I checked.. I have URB, I used CD-R, TDK manuf., source: costco, 700 MB. They look silver but I don't know what that means or the difference between the colors.
Good luck.

OK here's more info I learned this week.
Again, my car is a 2005 built within the last 3000 cars of the model run. It plays MP3's on the NAV unit with no problem. But I have had problems with the NAV lady giving bad directions.
I took the car to the dealer and they told me that there are two upgrades that can be flashed to the car off the GM computer. Your VIN determines which upgrades you need. Mine needed the second one for the GPS and they did it for free.
The dealer also told me that I needed to use the original NAV DVD and not the backup copy I had burned, because GM found that copies were not working properly.
Finally, the MP3 capability may be based on what type of CD burner you use. I use the Sony 710A which is compatible with all reading formats. Some owners who burned MP3's on single-format machines may be able to get their NAV to play MP3's if they go to a multiple-format burner.
Good luck all...

*ding ding ding* We have a winner. I'm not sure it was "mid-year" but Vert production was held up several times (IIRC) due to various top related issues.

I know that the RPO code and price on the nav changed between the time I originally priced my car and the time that I ordered it. Not sure, but that would have been between late Febuary and early April. I know 'verts were coming off the line in late March.

I just had my C6 (Nov 2004 build) in for the XM and complained about the Nav's poor directions. They found nothing wrong with the XM (didn't find a station for 1200 miles) but when I told them about the AVC not working, they ordered a new unit. They installed it last week and it does play MP3's.
Nav still has the 2003 disc though...

The vert production was delayed until December even for the ones with black manual top. They made the switch from U3U to URB long before vert production started. T

The radio option installed in the vehicle would not have anything to do with the top mechanism or color. The only possible way is if the wiring harness (which are unique to each build based on options) is affected by radio option and power top only.
Which, in all fairness, is what Buffy was saying.
