As a matter of interest, what were the specific reasons given for preferring the Garmin 430 over the UPS avionics? Did they replace all the UPS stuff, or only the GPS?
Pete – at the risk of budding in, I spent a great deal of time reseraching both Garmin and Apollo GPS units and while each have some advantages, I’ll bud in and tell you why I went with a 430 over an Apollo in my 260SE:
Garmin has STARS/SIDS - Apollo does not.
Garmin interfaces with the STEC GPSS option, and apollo does not.
In order to do dual nav receivers for IFR back-up, with Apollo you need a GPS and Two seperate radios. The 430 saves you space therefore.
The 430 has a larger/faster data bus which gives it an advantage for future applications.
The 430’s interface with the Sandel EHSI is far superior to UPS, allowing it to send map data/holding patterns…etc.
The 430 displays holding patterns on its unit, the apollo does not.
The 430 is WAAS upgadeable, the Apollo’s are not…
I believe the 430 can display certain types of traffic and weather data that the Apollo cannot. You need their mx20 map (which is an amazing product) to see that stuff.
Anyway, Apollo has some virtues to be sure, but those are Garmin advantages.
