Very recently I upgraded a 295 data base. It was quite an effort.
First off, while a MAC Communicator is available it does not work for aviation data base transfer. This I confirmed with Garmin tech support. Why do they provide a MAC communicator, I believe it is to upgrade NON aviation data bases, although that I can not confirm. I got the feeling the MAC-PC integration at Garmin failed and they may be fixing it, or not, I do not know.
Originally I bought a HP lap top just to upgrade Garmin and Dynon products. It worked great until MS came out with XP SP3. Garmin upgraded all their software to conform with SP3. My HP lap top was DOA with SP3. Its processor could not be upgraded.
That's when I called Garmin tech support, we have a very late IMAC that blows away most IBM-MS type computers but it would not down load a Garmin aviation data base with the communicator. The response I got was with some sympathy - but the 295 could not be upgraded with a MAC, any MAC.
I ended up imposing on a neighbor with a PC running with SP3, the 295 data base was installed in less than 2 minutes.
What a hassle, but I guess all that ends well, ends well.
