Garmin Updating - mutiple units

[LI32]

I have three different Garmin Units - 5015, 4212 & 545. Can I load all of the updates on one 2gb card, without confusing the units as to which update each needs; or do I need 3 SD cards?

downloading an update for any 4k/5k series garmin has all the family units in the update, plus all the perhiperals (radars, sounder boxes, gps antenna, etc.) load it once and you are all set. now as far as loading, you can let one unit feed everything in the network, but that takes a damn long time, at least the last time I tried, so I will update the individual heads individually, unplugging them from the network to update each one. Just leave one plugged into all of the perhiperals to update them if anything has come out for them

Then go back and load the update for the 545. Or buy another SD card online for less than $10.
