Hello Forum,

I have a 2007 Tahoe LTZ that I bought new just this January. I reside in Vancouver BC. I contacted the GM Nav Disc centre as soon as I got the new Tahoe home in January 2008 and they provided Nav Disc p/n 25850927.

Unfortunately this "updated" disc still did not have most of the road system updates for the last two years in my area. In fact it still thinks I park my Tahoe in a open field and will not allow me to properly program the "Home" location as it does not have the streets for listed for my 3+ year old subdivision.

I was told there might be another update coming out this July/August and that I should check then.

I have noticed that the NAV Disc Centre does now list what appears to be a 1/2 year update for 2008, p/n 25912408 [2008 1/2 CH/GMC900/SRX/DTS] although when I enter my VIN the system tells me I have the latest update [p/n 25850927]

Does anyone have this 1/2 year update or does anyone know when the next full update is coming out? I would really like to have a disc that at least shows where I live on it.

Thanks,

 

According to three different sellers on eBay, part number 25912408 is the latest nav disc available. Two of them have "Buy it Now" for $99
