I just bought a few of the Garmin's for my employees (limo drivers) theyre great because they talk to you and show you a clear pretty big screen and there is no flaws with it. You can get them at walmart for $299 and save $2000 instead of giving it to porsche for their nav.

THe biggest bonus is you can take it in any car you own, and stick it on any windshield (very securely) , most boxster owners have more than just the boxster so this is a big plus for $299 I guarantee you will love it, theres absolutely nothing wrong with it!

It really depends if you want to spend an extra $2000 to have the in dash look, which is very cool, compared to a stick on unit on your windshield.

I have an in dash unit on my lamborghini but it sucks because to be zoomed in on the streets you have to have the DVD Nav disk inserted and when you do that you cant play a CD, only the radio. You can view the nav screen when you have a CD in but its very far away and only shows what city you are in no streets, this is a brand new aftermarket unit that the dealer installed before I got it. Plus I don't think it talks to me, I don't really use it that much because I want to play CDs. I don't know if Porsches unit disables the CD player when using Nav.

I'm going to be leasing an 08 Hummer H2 soon - 400hp , a 6 speed instead of the old 4 speed and , displacement on demand looks to give it 20-30% better gas milage and I'm going to inqure about how much I would actually pay on a nav unit over the course of 3 years (figure out the payment without nav and with) and if its not too much then I may pick that up just to have the in dash setup, cause its a lease and maybe I only end up paying for half the nav price or something.
