Moonfire, that will not help.
Under accessories I posted about this issue a few days ago...
The issue his wife has is that when you buy the car dock and you dock the phone, you hit the home key and it automatically enters the dock mode for the car if in the car dock.
Here is the fix, and your wife will hate it, but she can handle it for now.... in a couple months we should get 2.2 with Google as a default.
Place the phone in the car dock and do not hit home. Already have it in the non-docked home screen. Once docked, open your application listing (app drawer) and manually select the Google Map application that you downloaded from the market. Now you can navigate with voice guide instruction with this application, use voice search for nav destinations and do what she had expected.
The whole issue with Bing Maps is not that the true Bing Maps software sucks, rather the problem is that we DO NOT have the entire Bing maps software! Verizon or Bing or Samsung...... someone.... decided to rip the voice guided mapping software out of Bing and instead give a totally useless Bing Maps POS that requires you to read the screen and also click step by step through the process of getting to the destination. It is a truely useless application, as I am 110% Verizon wanted!
By not giving you the full Bing experiance, they likely get a huge amount of low tech users to click on the VZ Navigator option and pay for the service. I completely believe that this is the reason we did not get the real Bing Mapping software.
I have an HTC Imagio (Win Mobile 6.5) with Bing and with Google both installed, and I thought Bing was A-OK, I prefered it over the Google maps. Both provided voice guided "garmin style" navigation, but I just liked the interface of Bing better. I defended Bing on this site prior to getting the Fascinate.
Then I got the fascinate and I immediately realized what everyone was crying about.... The stripped down, de-nutted, and useless version of Bind that the Fascinate has. It is pointless to even have this raped version of Bing maps.
So there you have it. I helped the guy and ran an emotional rant all in the same thread/reply! Multi-tasking!
