This was a fantastic thread. It saved the "old zumo"
I just received another replacement touch screen from:
eBay Member id: mingxing200808
FULL LCD Screen Display Garmin Zumo 400 500 450 550 79mmx 64.5m
Paid on May-21-12 / Shipped on May-21-12
He / She has done right by me twice now. A lot better than Garmin Support!!
YMMV, yadda yadda.
Thanks again to the folks that started this thread!
+1 - 3 purchases by me, good seller
My digitizer crapped out and this tutorial was fantastic. The only thing I noticed is that the torx needed to remove the 8 screws in mine were #6 not #7. I have a Garmin 550. Digitizer screen was easy to find on e-bay. I paid a little more to have mine shipped from Minnesota instead of China as I needed it quickly. Thanks for the great pictures and text.
My thanks also. I was thinking the 550 was a paperweight until I did some searching. It died on me this weekend. I placed my order!
Thank you!! Thank you for posting this thread.
My 550 did the same thing, no matter how hard I touched the screen the results were not what I wanted.
After a bit of deliberation, a phone call (39 minutes on hold, waiting to talk to someone) to Garmin, the best offer was the $150 refurbished unit. There was absolutely no deal to upgrade to a 660 or 665. Maybe others might have better luck, or have you had better luck?
I ordered off ebay, the ones shipped from Minnesota, glass and touch screen complete, delivered in three days for free. Okay the cost was $45, but it did arrive when stated, and it works fine.
The only difference I found was there seemed to be sort of a sheet of thin foam rubber all around the edges, instead of the formed rubber gasket that mine has had from new. I put the screen in with the new foam, instead of my old gasket, fits perfectly.
Having bought into the "Lifetime Maps" for my 550, I'm a happy camper that it's not going to be, as mentioned, a paperweight.
Again, thank you so much for starting and maintaining this thread!
I ordered the replacement screen and received it today. Installed it and up in running.
Thanks again for this thread.
This post saved me some hard earned cash
Got a digitiser off a Guy in London for £9.99 plus postage
Ordered Monday night Collected from Post Office this morning
and like it says in the instructions fitted in less than 20 mins
Thanks for thread!
UT OH . . is the BIG/center ribbon suppose to come unconnected? If so, how do I get it zipped back in? Thankx in advance ~
well, I got the center ribbon in . . . lets see if it holds up ??? GREAT INTO, thank you all who contributed !
I can't get the big ribbon to lock in. The white flap goes down but don't lock in. There seem to be no slot to slide in like the small one. Is it secured by pressure?
Never mind brother in-law got it for me!!!!!!!
Well, all's not well. My replacement Zumo screen froze up again. It worked fine for a few days into a ride then started having the same problem. Anyone have any ideas, how many have you replaced to get a good one? Are these replacement screens of lesser quality?? Maybe rejects??
Please describe the problem.
Last holiday my Zumo 500 started to freak out after 4 years and 40.000km, couldn't select anything and it started to randomly make new favorite locations.
Too bad I was 1100km's away from home and it happened in the first of 3 weeks holiday.
I made it home without any problems, but it was a long ride without my MP3 music
Last week I ordered a new screen + digitizer in Hong Kong (I didn't want to mess with just replacing the digitizer).
Hopefully this will fix the problem.
Still thinking about selling it and buying a new Garmin Zumo 660...
I don't take long trips, but I have decided when I do, I will bring a back-up GPS.
Basically the same problem I had before replacing the touch screen. After replacing the touchscreen it worked for a few days. The screen freezes up, No touch screen buttons work. One button will be a light beige color and not respond. Using outer buttons you can switch to a different screen but will default back to the navigation screen with speed, elev, etc. Gps still tracks route, I can upload the route to PC.
If two screens (old and new) are doing the same thing, I would look elsewhere for the problem, which probably means going to Garmin. They are pretty good about repair/replacement.
try reconecting the ribbon
OK, feedback and LESSONS LEARNED from one more successful digitizer replacement...<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
Symptom: Zumo 550 going crazy. Phantom screens popping up at random, impossibility to select a screen at will, incredible delay on all performed commands, screen freezing up, no touch screen buttons working, one touch screen button staying light beige in color and not responding, etc.<o></o>
Probable direct cause: damaged digitizer sending wrong selection instructions to the central processing unit and monopolizing all the computing power for phantom screen requests.<o></o>
Probable indirect cause: my Zumo 550 was purchased in September 2009 to be used in a Touratech vibration absorbing mount on my BMW R1200 GSA and endured 53,000 miles (so far), including a trip to Prudhoe Bay, AK; plus about a dozen outings mounted on a KTM 525 EXC in another Touratech vibration absorbing mount, riding the passes in Colorado (Engineer, Imogene, etc.) plus another dozen outings in the Arizona desert. The unit got a few scratches and started to produce phantom screens from time to time after 2 years of use (i.e. 2011), generally corrected by a cleaning of the screen. As the problem suddenly intensified this year I cleaned the screen with Windex and that essentially killed it. I SUSPECT THAT THE DIGITIZER IS SURFACE-COATED WITH A FILM THAT SEEMS TO TAKE ABOUT 3+ YEARS (depending on how much you ride) TO DETERIORATE NATURALLY, PROBABLY DUE TO UV RADIATIONS, AND IT SEEMS THAT CLEANING CHEMICALS (ALCOHOL?) PRECIPITATE CATASTROPHIC FAILURE TOWARD THE END OF LIFE OF THE COATING. <o></o>
Part used: I ordered the part USA Shipping -Garmin Zumo 450 550 Touch Screen Digitizer Glass 79mmx 64.5mm Item# 330732224800 from goodsupply0889 on ebay (http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=330732224800) for $26.98. I ordered two of them in order to have a spare - which proved providential (see here under...). The order was placed on Monday Aug 6 with UPS ground shipping. The digitizers were received in <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-comffice:smarttags" /><st1lace w:st="on"><st1:City w:st="on">Flagstaff</st1:City>, <st1:State w:st="on">AZ</st1:State></st1lace> on Saturday Aug 11. THIS IS THE CORRECT PART. THE SIZE FITS PERFECTLY THE LCD SCREEN AND THE CONNECTING RIBBON CABLE IS THE CORRECT ONE.<o></o>
Replacement work: I followed the process outlined by FrankS at the beginning of this thread and it worked perfectly with the following notes:<o></o>
1- As observed by many others, the proper Torx size is #6.<o></o>
2- My unit does not have a black frame (as described at the beginning of the thread) attached to the LCD display. That second frame - on which the digitizer is glued - is apparently silver in some units.<o></o>
3- I actually unglued the digitizer from this mounting frame without dismounting this frame from the LCD display as recommended. I am not sure why dismounting the frame from the LCD would make the work easier.<o></o>
4- To glue back the new digitizer on the frame I used a double sided adhesive product called CONTACT STICK sold at Home Depot in a package of five 1x3 strips and five 1x2 strips. You will find this by their Crazy Glue etc. products in the Paint section. The 1x3 strips are perfect to cut 4 thin 1/8 strips to place on all 4 sides of the LCD screen. This is the ideal product for the job but you better be sure to use sharp and clean scissors to cut it. This thing sticks like crazy...<o></o>
Mistakes to avoid: I made two mistakes that you can do without (especially the first one!).<o></o>
1- I am the guy who generally strips the Allen key round while over tightening screws, so I was not content to just press geeeennnntly the new digitizer down on the adhesive strips. I pressed hard with my nail around the perimeter to make sure the glue stuck ... and I cracked the glass of the new digitizer #$%^&!?!?!?!?! Good thing I had ordered two, I guess...<o></o>
2- I then became over cautious and did not insert deeply enough the LCD ribbon cable before latching it back in its socket. This resulted in an operating screen but without any backlight. I could only very faintly discern that the unit was actually working...<o></o>
Outcome: the Zumo now operates as new. I used the opportunity to update the Garmin firmware. You can do that by going to the so-called Dashboard at http://www8.garmin.com/support/collection.jsp?product=010-00567-00 with your unit connected to the computer with the regular USB cable.<o></o>
Thank you all for the help dispensed in this thread, and especially to FrankS for starting the ball rolling and the superb illustrated how to. <o></o>
