I'm sure it's exactly this. But it frustrating to the end user when I have my portable Garmin (that is over five years old) getting updates about once every quarter and the Ridgeline does not. The maps are built, but I agree Honda's contract with Garmin probably specified exactly how many updates and when. My original post was more to point out the irony of Honda's own software telling me it's time for an update on the maps but not having one available for download.True enuf, but ....
- Honda pays Garmin a fee to provide the nav systems for their vehicles (a license-fee for the firmware/software and its use, not suggesting Garmin provides the physical hardware).
- There's a cost associated with Garmin 'packaging and delivering' subsequent map updates tailored to the Honda systems (just as there is a cost for Garmin to 'package and deliver' map updates tailored for their own branded devices, which happens to occur at much more frequent intervals than for the Honda systems).
- For the period of 'free' map updates that cost is 'covered' by Honda through their license-fee agreement with Garmin. That agreement likely establishes the frequency that Garmin will 'package and deliver' updates to Honda's customers (the frequency of that effort likely having great bearing on the cost Garmin incurs to do that work, and therefore the price Honda pays Garmin for providing it to their customers, and therefore the price of Honda vehicles with nav paid by Honda's customers).
- It's quite likely that Garmin is capable of 'packaging and delivering' Honda system map updates more frequently if someone wanted to foot-the-bill for that (witness the frequency of Garmin-branded device updates which cost during any period of 'free' updates, including 'lifetime', is factored into Garmin's consumer price for those devices).
