765 Touchscreen

Put it back in it's box and return it. I had the same problem whit a 765 and exchanged it. This new one is fine and working great.

Have had my 765T for a year now and have never had an issue with the touchscreen. It works perfectly.

Thanks a lot for the info. It's been a tremendous help in me making the decision to bring it back. Unfortunately I had to explain to some clueless Best Buy employee what was going on (I think this was the last straw and I'm not shopping there ever again). I think once I showed him how to get to the diagnostic menus and showed him the touch screen diagnostics, he figured I knew what I was doing and gave the go-ahead for the return. Unfortunately they didn't have any more in stock so I had to get a refund, but I'll try to purchase it somewhere online. I love the unit, so hopefully the next one won't have this problem.

NH,

I just picked up a 765T (Amazon) and have no problem with the touch screen at all. I've seen posts by others with the same issue you had. They just recalibrated and (in most cases) the unit worked fine after that.

Cheers

I actually tried the calibration and unfortunately it didn't fix it. I always thought if the screen wasn't calibrated it would cause all presses to be off by some degree, and not have only some presses jump to a different area of the screen.

My 765t touchscreen was a little buggy right out of the box. The Garmen tech told me to recalibrate the screen more than one time. That helped it some. Later a firmware update, and a hard reset has it working even better. With only an occasional screen misinterpretation now. Yea, I realize that there are some units out there with more severe screen problems, and in need of repair, but for those with occasional problems, these fixes may help you.

Hmm, my screens was massively buggy when I got it, 755T, now just a little buggy on occasion after a calibration, will have to try the diags and maybe a 2nd recal and see if it helps any.

When I returned my 765T to Best Buy I had the opposite experience. My clerk thought she knew everything about the Nuvi so I was drilled with the "did I's" and "didn't I's" before I finally got mine exchanged. Either way, I'm with you ... No more Best Buy!
BTW, my touchscreen is a bit touchy too. Calibrate, grit teeth and keep on navigating.

Well there's no way I'm ever purchasing from any store that I know is going to fight with me to return a defective item. I've never had to "prove" before that I had a defective unit. What are you supposed to do if you had a unit that reboots every 3 days? Wait for it to happen so they can verify that it's broken and give you a speech about how these devices aren't perfect? I don't think so. I bought my new one from NewEgg and I've never had any trouble with them. Hopefully I won't even have to worry about returning it.

My father just bought a 775. There is definitively a problem with the touchscreen. I could not type anything fast without getting a typo, or worst hitting a meny key or factory key. I never got this type of problems with my 760.

I'll try to recalibrate the 775 next time I visit and maybe do a fw update.

I've done 2 recalibrates and a hard reset on my 765t and it is better than before this was done. It certainly can't hurt

Agreed but some screens are just plain bad. I had to return two units before I got one that was actually usable. Numerous calibrations were done but simply did not help in the least bit. If the calibrations do not help, return the unit as being defective because many of the units actually are.

I guess we pay the shipping and insurance twice in order to get one that works!!! Boy, is this company getting away with it!!!

I just got in my new 765t and I'm having the same issue, if not worse. Now I'm seeing this jumping on the bottom left of the screen in addition to the top right. If I go to search for an address, and start typing 3 repeatedly, it jumps to 6 sometimes, and even when I touch the eraser repeatedly, it sometimes registers a number way below it. I guess I have no choice but to return this one too, but I don't know if I should do it through NewEgg or call Garmin. I'm of course worried that Garmin will send me a refurbished unit, and I'm worried the batch that NewEgg has may all be bad. I'm really disappointed that the nuvis have this issue. It should recognize where I touch 100% of the time, and to have 2 units in a row with this issue is quite annoying.

I was a tech training developer for a car company that used a diagnostic PC with a touch-screen. One day a trainer asked me to come into his class to see this- One of the students had been undergoing chemotherapy and said that once he had been on it for a few weeks, he couldn't operate the machine anymore. Sure enough, when he touched it there was usually no response, but sometimes it would 'jump' to an icon next to, but not under his finger.

He said using hand moisturizer helped, but wasn't perfect. We also had problems when using nitrile gloves- erratic and inaccurate operation.

Having said all that, I'm just throwing it out for what it's worth. My 765T is usually OK, but sometimes it 'jumps' and I've often wished I had some moisturizer on hand to try.

An afterthought- Anyone tried a PDA stylus to see if it helped? (I haven't).

And I actually tried using different thing, including my finger, the back of my fingernail (which is how I usually use touch-screen devices), the plastic end of a pen, and a napkin wrapped up to make a point. All of them did the same thing, so it appears no matter what I use it doesn't help.

Enter the nuvi diagnostics mode (press battery icon or it's location if externally powered for ~10 seconds) and advance through the pages to a black screen with a blue dot when touched. This is the touchscreen test page. Press and hold any spot on the screen and the blue dot will follow along with a display of the dot's coordinates. Ideally, the dot should not move more than 2mm or so when you press and hold the screen. Bad screens will have the dot "jump" to random locations.

It will not matter what is being used to touch the screen...the dot will jump regardless if the screen is bad (or not calibrated). Calibration will only help so much if you have a bad screen.

DorkusNimrod,

Thanks for that precision. I'll test my dad's 765 that way.

I just did the test and it looks like I have a good screen. I have no problems so far.

It is certainly annoying to have to prove to a store that you need to return an item. But I imagine this time of year they are getting *many* returns, so I can't blame them for putting a little pressure on customers (though just a little). For me, I would still consider buying from a brick & mortar place like Best Buy or Sears because of the ability to (relatively) easily take things back. It beats having to deal with shipping back to an online place. Please don't misunderstand: you can of course get some great deals online, and I certainly am not saying brick & mortar is always the right choice. But there is a time and place for everything. Keep your options open.

One more thought: ever done the cash back thing via Bing? Search for items via Microsoft Bing, and sometimes you can get a small percentage back in cash. If you couple that with picking up in-store, sometimes this can be a viable option for shopping.

I often wonder how some of the stores can even stay in business, with all the returns - and wacky reasons - that they get. It's a real education to listen to others in the Customer Service line sometimes.

Unfortunately that's way of Garmin...and imagine... some customers are even thankfull...I never had a gadget that gave me so much trouble as Garmin 765t so far...and when I needed it most it bricked...the last Garmin for me that's for sure...

That's actually what I showed the BestBuy employee and I showed him how it jumped to another part of the screen when I pressed in the top right corner a bunch of times. And I didn't have much issue with the dragging. It's if you keep hitting in one area of the screen, eventually the dot jumps way below where you touched, or to the left. That's what this new unit is doing as well.

I get that they want to verify that the buyer of the device isn't returning it for something they should have known. But when the employee starts giving a lecture on how internet complaints are always inflated to try to defend it instead of testing it, it's called BULL. And when I know a TON more than that person and have to teach THEM how to use the device. Again, BULL. That's what you get with BestBuy. I'm a computer tech and programmer, and I've gone in and asked simple questions to show other people how they know nothing of the area they are working in. That's why retail has declined IMO, to the point where I don't want to deal with it anymore. I once asked a guy in the TV section about the black levels of LCD TVs, and he had no clue what I was talking about. I should have sealed the deal and never gone back at that point.

my 765t was so bad if I hit show map it would give go to, calibrating the screen fixed that problem, but with the delay typing and not always getting what I hit, typing needless to say is a *itch.

I hate to say it but the 765T is a brick if you update it to 3.9 firmware release. I had two and took them back.

My touch screen is so bad I can't even erase the bad characters it puts in when I am trying to enter an address. There doesn't seem to be any area on the screen that is close to accurate. I have calibrated it many times but nothing works.

Mine is not as bad as yours but, still I can say without shame that purchasing of this gadget ( Garmin Nuvi 765T ) is a waste of money...in other words... you are not getting what you pay for...

Hopefully, the successor to the 3.9 SW will be out soon.

Garmin, are you listening?
