Navigation and USB problem on brand new 370z!!

[atx370z]

First of all I gotta say I'm kind of disappointed. I've had the car for 3 days and I'm having a couple of issues. I'm hoping someone here can provide some insight before I take it back to the dealer tomorrow. Here are the 2 issues..

1. Navigation system only finds some of the streets I put in as destinations. On 3 occasions it hasn't found the address and I had to use the gps on my phone. Quite disappointing to say the least. Anyone ever had this happen and is it something as simple as an update from the dealer??

2. For the first couple of days my iPod worked fine. Now it says, "check USB memory or iPod" and won't play. I found 1 person with a similar issue by seearching and he said Nissan has a software update for it but only for the roadster. The won't install it on the coupes navi, so they are replacing the whole unit. I don't know about you guys but I don't feel comfortable with the deAlership tearing apart the dash on a brand new car. Anyone else have this issue??

Any input or thoughts are much appreciated. Thanks!
