Software update card not included with my GMR radome

Garmin has stopped including software update cards with new radomes. The reasoning behind this change is that the software release that made chartplotters compatible with the new radomes was released quite some time ago (October 2013). Newly purchased and installed packages should have no problem working out of the box.

If you install a new GMR 18 xHD or GMR 24 xHD and your chartplotter does not recognize it, first please verify your chartplotter is compatible. You can do that by going to the product page for your radar (GMR 18 xHD/GMR 24 xHD) and clicking the Compatible Devices tab. If it is compatible, download/purchase and install the latest software for your device here.
