Just purchased a 1030 as a replacement for a 1000. First thing I did was put the latest 3.80 F/W on it. Works OK when just being used to record a ride, but...
1. Garmin have perpetuated the problem on the Australian 1030 that existed on the Australian 1000 - with the basemap they supply, T-B-T navigation does not work with OSM maps - it works OK with the map that Garmin supply, but as I'm shortly going cycling in Europe and will be using the Velomap maps, I tested with the Velomap Australia map. The supplied basemap is 48.5Mb and is identified as "INTL standard Basemap, NR". If I disable the basemap, then T-B-T navigation starts working correctly. See attached screen shots - with the basemap enabled, the street name and turn direction area at the top of the screen is blank. With the basemap disabled, the data appears. If I rename the basemap in the Garmin folder on the 1030 and copy in the gmapbmap.img from my old Edge Touring, which is about 1/10 the size (5.75Mb), then I can enable that and T-B-T navigation continues to work correctly. The original discussion concerning the same problem on the 1000 is at https://forums.garmin.com/forum/into-sports/cycling/edge-1000-aa/123750-.
No T-B-T directions with basemap enabled
T-B-T directions appear with basemap disabled
2. Access to the SD card when mounted in the 1030 is many times slower than if I remove the card and access it via an SD reader. I had to use a 32Gb class 10 SD card for the Velomap Europe map as there was insufficient space for it on the 1030 internal memory. I initially tried installing the map from Basecamp to the SD card while it was mounted in the 1030, which was attached to a USB3 port on the PC. I stopped the install after several hours because it was still only about 20% complete. Copied GarminDevice.xml to the Garmin folder on the card, deleted the incomplete map files from the card, then removed it from the 1030 and re-ran the install with the card in an SD reader. The install completed inside two hours.
