daveo,
I didn't use a T4 or a T5 screwdriver, I had a small flat blade driver for eyeglass repair and it worked fine.
I once RMAed a video monitor to ViewSonic and they lost it for 6 months.
Garmin is going to be overrun with returns! |

Well, I bought a T5 torx driver this morning and opened up my 755T.
Had it back together and updated in less then 10 minutes.
I wasn't prepared to pay to send it back and be without it for 2 weeks (at least). |

Made a tutorial for opening a nüvi 7x5.
Because some of my colleagues are just.. let us say.. incapable.
Tools used
- Wiha Precision ESD TORX PLUS® Schraubendreher. 5IP x 40
- Plastic flat tool
Unscrew both torx screws
Use a plastic tool to unlock the cover
Work your way around the unit
The top side of the cover has 3 locking points and the sides 2
Release the battery connector for atleast 30 seconds
Rebuild your unit and connect it to your computer
Install the update via WebUpdater
Wait... :D
Voila! |
garmin is the way.

| I went to Lowes while out visiting clients and stuff. Took longer to pry case apart and back than anything else. Use a PC small flat head and an old credit card. Took a couple tries to get it back together, but thanks to all for sharing. I was post 2 on this list. I agree with the above poster - I might not see this unit until AUgust if I sent it back and I do work on PCs, so it was just a matter of scale for the screws. The connector for the battery is a common one. |

| Here is an odd result from the update. My 765t has been pretty fast acquiring satellite signals (usually under a minute on cold starts and only a few seconds on warm starts). After the update, I'm acquire the satellite signal much faster (cold starts are a few seconds, and that is inside my house). I thought this fix disabled "hotfix". |

Mods: maybe v3.60 firmware observations should be in a new topic? There may not be much to discuss yet though since it was seemingly only a bug-fix...
Here are a couple of personal observations of 3.60:
1. For me, sat fix time seems about the same with no difference one way or the other in performance
2. "Slide" effect between screen changes along with map redrawing is noticeably smoother. Overall feel of the unit seems snappier.
I recall a few posts stating that user's recent NIB 7x5 units came factory pre-installed with firmware 3.50 (not a typo, 3.50) which would be an internal Garmin release. It could be that there are more bug fixes/tweaks/new bugs carried over from 3.50 in addition to the main "GPS sat fix" correction that is being reported by Garmin. They have done this in the past.
No one knows for sure what Garmin's fix for the "GPS sat fix" issue was except for Garmin themselves. If HotFix (or AGPS) was disabled or not is unknown. |

| My 765T is alive again, it was bricked. Thanks to SergZak and bluzark for sharing the fix. I was afraid to open my unit because It's 2 month old. This procedure saved me about 80 USD for shipping for repair (I'm in South America) |

| Thanks to all on this forum for the help in explaining what the 7x5 problem was and how to fix it. My 6 month old 755t started to fail yesterday with power and satellite issues. Today it could not acquire the satellites and then would not power up. Luckily I held the power button to the left for 12-15 seconds and it powered up, on the battery. Immediately did the Garmin web update, and all went well. Used the unit this afternoon, and it was back to its normal operation. You sure miss it when its not working/available. |

I received an email from a Manager at Garmin today saying:
"
I was attempting to get your gps out tonight and expedited however I received a message back from the warehouse indicating that we do not have any 7x5 series in stock that is ready to go out. Unfortunately all of these devices including new ones have to be reworked to get the issue resolved. I did notify the warehouse that your device is expected to arrive in our warehouse tomorrow. I did find out that we might actually be doing repairs on these devices so if you have any favorites saved, those will still be available. I want to clarify that this option has never been available until today as we don’t have enough stock on hand to exchange everyone’s 7x5 device and the fix is simple.
The good news is since we know what the issue is and how to correct it, it should be resolved fairly quickly and you were able to get your device to us in a timely manner. We process each exchange in the order they were received, so hopefully, you should be taken care of quickly.
"
I responded, asking what she means by "all of these devices including new ones have to be reworked to get the issue resolved". |

They likely need to reflash ALL of their stock (both new & refurb) to the 3.6 firmware version.
I think this is a first for Garmin...not enough stock (new & refurb) for the literally thousands of exchanges. So now they will actually *repair* (not send a refurb) your unit which will involve exactly what others have been doing with their bricked 7x5's. That is, open the case, unplug the battery, plug it back in and flash v3.60 to the unit. |

hi,
i want to share with you my experience. I bought brand new 765 on 09/06/23. On the same day I found this forum, so I avoid to use my unit for navigation. Just to be on the safe side, I renamed those two files mentioned by Sergzak and waited for release of new firmware.
Yesterday I did the update for 3.60. Everything looks fine now. I have checked those file and found out, that the new ones installed are exactly the same size as previous which I have disabled.
Before the update I had the firmware version 3.50 (which some of you mentioned as unpublic).
That leads me to the speculation, that maybe not all the units are hit by this problem. I have a friend, he bought the same model few weeks ago, he also has a 3.50 installed by default a experienced no problem over the last week.
I dont know, whether my conclusion is correct. If you have the similar ar opposite experience, please comment. |
