Yes, I asked Garmin for status update. Then they asked me to send the video again. Then I sent again and asked about the ticket they supposed to have opened already. Then they replied, yes they have opened and it would be a question from development team. Haha. Snakes working at Garmin. For me it's part of "keeping the customer busy while we have no fix for the problem". You can find (not very more) info in other forums as well. All Garmin Galileo/multiband units (65 & 66) seem to have the problem. I hope links to other forums are fine here - it is how internet works: https://www.gpsrchive.com/Discussion/viewtopic.php?f=69&t=1262 https://www.gpsrchive.com/Discussion/viewtopic.php?f=36&t=1278 https://www.naviboard.de/thread/66127-kein-galileo-empfang/?postID=531727

Another disadvantage for touch is that it cannot be used with gloves.

I think the relation is as follows: - CPE.BIN present: satellites keep flashing - CPE.BIN not present: no satellites will be received Temporary workaround: trigger AutoLocate Meanwhile Garmin told, they would not know about Galileo or GLONASS issues.

Doesn't work. Galileo and GLONASS are still lost after some time. That trial, also restarting the unit has not brought Galileo or GLONASS back working.

I wrote in English to product.support Garmin email and got answer in local language. Instructions: 1. Check for updates in Garmin Express 2. Factory reset 3. If not resolved, unit is defect, send in for replacement, we already issued an RMA for you As expected, I landed in 3. Obviously they have had a look in the files I have sent them (I sent as as per gpsrchive.com). Serial number was properly registered in the RMA without any further action from my side. New unit: serial number 900 units incremented (still below 3000). Firmware 3.50 (old: was updated to 3.70). Other version numbers are same. From RMA I know I have an EMEA version of the unit. Actually I wanted to go step by step, one change at time until I run into the same issue again. But some time Garmin Express updated me the Firmware without my confirmation. My current assumption: As long as Garmin\GPS\CPE.BIN is on the unit, it will malfunction. This is placed on the unit either by Garmin Express when the unit is registered to a Garmin account or by connecting through Bluetooth to smartphone. I noticed that, because the new device hasn’t had the file initially and seemed to work well out of the box. CPE.BIN will not be erased by factory reset. It need to be deleted manually. I’ll put few more investigations on that issue. Preliminary workaround which seems to work: - delete CPE.BIN - factory reset (probably not required) - switch GPS to demo mode, trigger AutoLocate, switch GPS on (will clear position and satellite data)

Validated and confirmed!! It's reproducible. Tested today: 11 hours after switching on the unit, only GPS is left. GPS is received with all available satellites. (checked with https://www.gnssplanning.com ) Not sure whether it relates to "Galileo stops flashing" or satellites get dropped earlier, but this is the general observed sequence. The last received Galileo satellite appeared at a very wrong position on the sky map before it dropped (at the border - actually it was ~70°). Earlier it was correctly displayed. Turning off the unit and on again, all satellites are back again and in proper position. (Galileo keeps flashing) Sure. I'll track it until Garmin fixes it. If they will be slow and / or don't reply to my bug report accordingly, they get a poor Amazon rating. Deserved. As of now I would recommend: don't buy this unit unless you get it with good discount. Wait for bugfix.

I think I have found a systematic behavior - I'll observe it further: - Usually Galileo keeps flashing - when it stops flashing (e.g. after 3 hours), then - Galileo and Glonass satellites will disappear during the next hours (e.g. 3 hours) - No new satellites for Galileo and Glonass will be found anymore I compared to eTrex Legend HCx with DGPS active. I already reported the Galileo issue to Garmin.

I don't think it's an UI issue. I would expect less drift in some edges of the forest when only 2x L5 GPS but 6x E5a Galileo are available.

Thanks for that link! Also how to report bugs to Garmin! Actually it also happens with GLONASS. But Galileo I have noticed more severe in the meantime. GPS usually works well. And refer to first post, it can loose satellites which should have been back receivable in free field. I have bought this unit due to Galileo multiband support. I am mapping for Openstreetmap. Due to that issues I am not yet fully satisfied with the purchase. I have also noticed Bug #7, probably will never be fixed.

In "Satellites" view, many Satellites keep flashing - which means with my eTrex unit, not used for position fix. For example in best view to sky, 6 Galileo full strength E1+E5a and flashing. GLONASS and GPS no flashing. Video: https://c.gmx.net/@327045630402759059/ZDT2ap8bRhmlm1vxoiRC-g What does it mean? Is Galileo not used by the unit? Firmware is latest: 3.70

Hello, I have a GPSMAP 65s unit. It is unreliable in terms of receiving Multi-GNSS. GPS is always received. Galileo and GLONASS is unreliable. One day lots of satellites, the other day no satellite despite unrestricted sky view. Restarting the unit doesnt fix it. I consider it appearing somehow random. Today, I went on a hike in the forest. In the beginning few Galileo and GLONASS were received. Hours later, the connection dropped, no satellites in view. Even when in free field. The unit is up to date through Garmin Express. Any same observations among other owners? Any known fixes? Regards
