A good GPS system of any kind works best with touch screen or a button next to the screen itself for menu. If you're looking for stand alone unit which I doubt you are, Kenwood is a good unit. It's very user friendly. I havent had the chance to play with Alpine unit since someone broke the Alpine screen and stole the map data DVD at the store I work at. Kenwood unit has touch screen for all the menus plus it speaks perfectly understandable English. The next best thing for a computer software based GPS nav is Copilot2003. It does about 90% to 95% of what you're asking for. Street Atlas is also good but requires at least a SVGA display. Copilot works best with SVGA also but it is very readable if VGA or composite RCA jack LCD monitor is all you have.
- Has all usa maps
Copilot and Street Atlas both have that.
- Shows my position on map as I move about.
Copilot is only good for step by step navigational use. It's not good for showing current position while you drive unless you enter a destination.
SA is good for displaying your current position on the map with out entering a destination but step by step navigational use is questionable.
- Allows input of address for door to door guidence.
Both have that. Copilot searches faster and has onscreen keyboard which is perfect for touch screen users.
SA searches slower but has more results. SA requires a keyboard.
- Has voice guide. (turn left in 90 seconds/feet whatever)
Both have that. Copilot's voice is the worst feature of the whole setup. It sounds like a rebot and male is unchangeable unless you delete it then Karen Watson (female speaker) takes over. But the information it tells you is really good.
SA has a better voice but still sounds semi robotic. You can change the speech engine and the speaker, meaning you can download a speaker with a British accent.
- has automatic re-routing, so if I miss a turn, it reroutes my path and gives directions on how to get back on course
This feature is where Copilot shines. It reroutes automatically. You don't have to do anything for it to reroute.
SA has semi-automatic re-route. You have to manually click on the "Back on Track" button everytime you missed a turn. Half of the time, it tells you to make a U turn. Not good for someone with an RV.
- Has some degree of voice response (so I can ask it stuff, like "zoom picture out")
I don't have a mic so I dont use this feature but both have that.
-Can I enter addresses by voice (vs keyboard/keypad)
I realize you have a stick but are you sure you want to enter an address while you're driving? Since I dont use the mic on my setup, I couldnt tell you if you can use voice to enter destination.
I tried using Street Atlas 2003 Plus with Copilot GPS receiver and it didnt work. If you want to use both Copilot and Street Atlas (one at a time but have both installed) you need to get Rand McNally serial GPS receiver. Both software work with the Rand. Copilot is very picky on what GPS receiver it uses. The only other known GPS receiver that works with Copilot is the Rand McNally.
I started my system thinking that I'm only gonna use it for MP3 player and Navigation. I never knew it turned into "I use my computer for EVERYTHING!!!."
I know you're new so if you have any questions feel free to ask. Also check out other people's installs. It might give you some ideas. This is my install.
