Now since the Zodiac is the only Palm (that I know of, someone correct me if I'm wrong) that has two card slots, this means it's the only Palm in which you can put NavCard in the SD slot, and an SDIO GPS card in the second slot, and have voice-prompted, real-time GPS navigation and mapping of the entire USA on a single device with no cables or external anything required.. pretty sexy stuff..
The ONLY seller/maker/purveyor of an SDIO GPS driver for PalmOS is iGolf Technologies - igolftech.com
They sell the driver alone for about $25.00, or the driver in combination with a Panasonic SDIO GPS card for about $250.00.. yeah, it's pricey, but if you want the whole country on a single card, NavCard is the only solution, and if you want both cards in a single device, a Zodiac is the only way it can be done, as far as I know.. NavCard works with other modern Palms, but they require an external GPS receiver..
The only problem is the lack of a Zodiac DC car charger / cable.. I don't know why Tapwave hasn't released one yet, but we really need one.. so although the SDIO GPS card uses very little power, if you set NavCard to leave the screen on for an hour (same setting that regular Mapopolis has).. and use voice prompting for turn-by-turn navigation, your Zodiac's battery will say seeya later in an hour or two..
Anyway, these are two pretty cutting-edge products.. if you feel like ponying up about $300.00 (including an AC > DC power inverter for use in the car if you plan to keep the Zodiac powered on for longer than an hour or two while navigating with voice prompting).. then there ya go..
They're not the equal of an in-dash GPS system, but then those cost $1500 to $3000 in new cars, and they're not portable
Yeah, you can spend $1000 on a Garmin Street Pilot to plunk on your dash, but try carrying that around with you outside your car, plus it's a single-purpose device..
NavCard uses the NavTeq 2005 mapping data.. now if you want to see something really slick, check out http://maps.google.com - play around with it for a while, it's truly amazing.. and it uses the same data, although it's a helluva lot faster than on a PDA, you'd expect that.. but.. there's no way to make Google's NavTeq mapping link to a GPS unit, if, for example, you wanted to lug a laptop around with you in the car..
Try using it to plot a route from your home address to the White House or Disneyland or anything coast-to-coast and see how fast it is.. find your address and then ask it to show you every McDonalds near you or every ATM, school, supermarket, Mexican restaurant, whatever.
NavCard doesn't have ALL the POIs (Points of Interest) that Google has, simply because there is a limit as to how much data they could cram onto a 1 gig SD card. It's pretty remarkble that they could squish the street level maps of the whole USA onto a 1 gig card at all.. With a 2 gig card, they could literally have ALL the data, but then the product would cost twice as much..
Anyway I've been playing with NavCard and SDIO GPS in my Zodiac 2 and SDIO GPS with regular Mapopolis in my Treo 650 for over a month.. any questions, just holler, and time-permitting, I'll try to answer them..
IMO, this is a "killer app".. simply because with its two slots, the Zodiac is the only Palm in which you can put both these cards at the same time..
