Quadra Update
After several e-mail message exchanges with Anywhere Map, I have some updated Quadra information for your information and comment:
The Quadra’s screen brightness is 380 nits. I don’t know how this compares with the Aera; my Google search skills must be meager! The AV8OR Horizon 3D has a screen brightness of 300 nits, but I could not find the screen brightness spec for the basic AV8OR. My guess is that the Quadra, Aera, and AV8OR all have about the same screen brightness; equivalent to the typical automobile touch-screen GPS and limited by their portability/battery life. Of course, an in-person, side-by-side comparison would be best to check the relative screen brightness.
Also, although the Quadra has no external antenna direct plug-in, Anywhere Map sells a Haicom Bluetooth GPS ($149) along with a 2-way vdc splitter ($15). On the main webpage, look under “Products” then “GPS Units” for the Haicom and “Products” then “Power Accessories” for the splitter. Of course, you can buy the splitter just about Anywhere (no pun intended!), and there are probably other, less expensive, Bluetooth GPS products that might work just as well as the Haicom.
Quadra External GPS Functionality, at least as far as I can interpret Anywhere Map’s responses to me: The Haicom communicates with the Quadra via Bluetooth (WiFi) and provides WAAS-enabled GPS data to the Quadra. The 2-way splitter powers the Quadra as well as continuously recharges the Haicom’s batteries. I don’t know if it’s good to have Bluetooth/WiFi running around the cockpit, but that’s Anywhere Map’s alternative to a plug-in external antenna.
Well, anyway, I hope this info helps clarify Quadra’s position in the aviation portable GPS market. For me, since I would like to panel-mount my portable GPS, I would like to see the Haicom’s capability demonstrated with no Quadra or cockpit “hiccups.” Also, I would like to personally check the Quadra’s screen brightness vs. the Aera and AV8OR. Maybe someone on this forum could give us all an “Airshow Report” at the next opportunity (Sun ‘N Fun?).
For the Quadra, by the time you add $200 for the sectional map capability, another $165 for an external GPS signal source, and possibly another $200 delta for the EFB capability ($1,165 total), you start to approach the price of an Aera 510. On the other hand, except for the lack of an RS232 interface (a deal-breaker for those relying on their portable GPS for autopilot guidance and other communications), the Quadra provides strong specifications and an excellent feature set. When you also consider the low cost of the Quadra’s updates, the Quadra appears to come off very well, IF the Haicom really works and the screen brightness is acceptable.
In Summary: I suppose the whole aviation portable GPS marketplace boils down to “Different Strokes For Different Folks!”
My Personal Opinion Only!: IF, and ONLY IF, the Quadra comes through with respect to the Haicom interface and screen brightness, I’ll buy a Quadra. For my requirements, the Quadra has the best feature set, and I really like the low-cost updates. Otherwise, it’s off to Aera or AV8OR land!
