Ah, a good point that would've never occurred to me in my world. Makes better sense now, and explains why, at least for my 550, GarminExpress 6.8.0.0 and 6.7.0.0 doesn't work, but 6.6.0.0 works just fine.

Couldn't agree more. One would think Garmin's engineers would appreciate leaving well-enough alone. But, like Advnzr, what do I know? A shame we end-users get stuck with cobbling together solutions to issues that should come directly from the manufacturer; they have the time, money and resources ...

Problem solved!! Advnzer - you nailed it. I uninstalled MapInstall 4.1.1, then found, downloaded and installed MapInstall 4.0.0. Installed the 2019 US maps to the original 16gb SD card I started this exercise with, and plugged it into the 550. Powered it up, and IT'S ALL GOOD. Everything. The "Map ...

Well, here goes... 1. MapInstall 4.1.1 loaded the state of Maryland directly to the 550 with no issues. Had full functionality and features. The "Map Info" button displayed the 2019 file info for Maryland, just like normal. Don't think bad firmware is an issue. Things looked promising. 2. Inserted ...

Advnzer, I think your instructions are referencing use on a PC and I do believe that Whistler is working with a MAC. Whistler, you do have the gmapbmap.img file in the Garmin folder on the internal zumo storage? IIRC, the base map files are needed on internal storage and then the gmapsupp.img file ...

One other thing. All devices are limited to the number of map tiles installed. You don't also have any other maps installed do you? No other maps installed, sussamb. The two 2019 map files (the .gma and .img files) are all that's on the SD card in the "Garmin" folder. No maps installed on the 550 ...

Carolina - will take a look after work and see if the 550 has Map Info and confirm the map version. Sussamb - yep, the SD card was formatted to FAT32. Advnzr - will give the MapInstall-only downgrade a shot. Thank you for the info and links. Thanks again for your help and patience, folks! Will post ...

Well, here's the short version...nothing worked. Here's the longer version... First, I'm very grateful to everyone for your effort and input; I greatly appreciate your time and trouble. Anyway, I tried Carolina's tutorial first. Followed it to the letter. It all made good, logical sense to me and ...

Hmm, very ineresting, Advnzr. I'll check out the link you sent after my workday here. I did indeed use the same procedure last year when I updated my Zumo with the 2018 files. I made sure I copied the files into their respective folders on the SD card, and everything worked like a charm. Things do ...

Hey, Everyone. Have a small problem that is really frustrating me at the moment. 1. Decided to update my maps for my 550. Removed the SD card and loaded it into my Macbook. Saved the 2018 .gmap and .gma files to my hard drive, then erased the SD card. 2. Opened Garmin Express, found the 2019 map ...
