Just received my upgrade disc 7.2 for my 06 350Z. No instructions so I just took the old one out & put the new one in. Problem though the old one was more accurate. For example a street that the name changed last year on the old one showed up as the old name but on the new one it shows no street. Also on some streets it used to say the name of the street taveling on but the new one shows on that street unknown name. Am I supposed to do something besides putting the disc in the unit.

 

Question???? Did you have to purchase this disk...... Or was it given to you by the dealership???? The reason I am asking is because I live in Jacksonville, FL and Roads are being built daily..... I would like an upgrade but I think that when i check the dealership wanted like 500 bucks for just the disc.

I bought it. Was sent a postcard that it was out & ordered it, I believe it was $145.00 + shipping.
