I just ordered this same unit from TigerDirect.com...haven't received it yet. I was looking at TigerGPS as well, but they are in-state for me and thus I would have had to pay sales tax.
Incidentally, I asked the TigerDirect salesman if they are an "authorized Garmin dealer" before making my purchase because Garmin requires you to purchase from an authorized dealer for warranty and software update purposes. The salesperson said that TigerDirect is in fact an authorized dealer, so I placed my order.
Just to be sure (obviously, a little late) I contacted Garmin and much to my surprise TigerDirect is NOT an authorized Garmin dealer. The Garmin CS rep however said they would honor the warranty and allow me to upgrade to V8 at no charge!
I should have the GPS by the end of the week. This will be my first non-aviation GPS.
By the way, here is the list of Garmin authorized online retailers. TigerGPS is not listed.
Did you have any problem registering and upgrading the City Navigator software?
TIA.
