Garmin StreetPilot 2610

I'm actually thinking of buying this instead of getting nav.. Save $1500. I know it doesn't look as nice since it's not BUILT-IN to the car.. but is that really worth $1500.. come on now.

 

Whatever you get make sure it integrates with the vehice speed sensor otherwise you get "blackout" areas such as in tunnels, along streets with tall buildings or even mountainous areas. The advantage of the built in Acura Navi is that it is connected to all the TSX's sensors having to do with speed and direction. It is, therefore, very accurate. It's also very cool the way it controls the A/C and sound system. Voice activation is also great. ...Sorry, but I'd say it is worth the extra $1500.

 

 

Trust me... get the NAV. It is well worth the money spent. Aftermarket NAV will run a bit less but the custom installations, etc. And also you won't get the cool features that comes with stock NAV such as A/C control, calendar, computer trip, etc.
I had the option to take the NAV but I chose not to. because I thought that $2000 is too much. Now I'm paying the price!!! If I want to add after market NAV, it will cost me $2400 (with the customation that I want). Just my $0.02
