    News: I heard back from the person, and he says he will send me another touch screen if I tell him the correct size. Again.

    An update; I received my 2nd touch screen from our Man in Hong Kong yesterday. Not only was it the correct size this time, but it was already mounted in the frame, so I didn't have to dork around cutting the old screen out and gluing the new one in. I have no idea why some of us have received different products from this supplier, but I am glad to report that "we do the happy and successful transction".

    All hail Frank S, pretbek, and GS Addict for showing the rest of us the way.

    More info for those that want to try the Zumo 550 screen-ectomy:

    I received both the incorrect screen (too small, connector in the wrong location) and the correct screen (79.3mm x 64.77mm aka 3.125" x 2.550") from "Yang Lin Sen" at "Espeed Logistics Int'l Ltd." in HK. He and I emailed back and forth from the "mingxing200808" link on eBay. I believe he is the same seller that GS Addict bought from.

    When I told him that the first screen was too small, he replied after a few days, and I told him the correct size again. The second screen arrived in less than two weeks, a week sooner than he had predicted. He has not asked that I return the first screen, or asked me for more money.

    FWIW:
    Part number on my old touch screen = 402D 035-41 DA
    Part number on the 4 pin connector = A68-D35BA402D 750006400722 0264

    Part number on new touch screen = 402D 035-25 BE
    Part number on new connector = A68-D35BA402D 710014410703 0 ?? 72 (the third digit was obscured by black ink.)

    If you receive a replacement touch screen already mounted in its frame, it's a snap-fit onto the LCD screen. The trickiest part for me was to gently bend the black frame of the old touch screen a bit on all four sides so it would un-snap from the LCD screen.

    When re-assembling the 550 case and the guts, the 4 pin connector on my touch screen came out of its socket twice as I was positioning the pieces together.

    I didn't have to re-calibrate the screen; it worked correctly when I powered the unit back up, but I shut it down and re-calibrated anyway.

    There were small scuffs and scratches on the metal frame of the replacement touch screen, it may have been "refurbished", but it seems to work okay. So far.

    Again, my thanks to Frank S, pretbek, and GS Addict.

    I too am having the touch screen going crazy syndrome.:eek1 I can't complain to much because I have had this 550 for about 4 years now!. :thumb

    I'm torn on doing the flat $150 refurbished swap or replacing the touch screen. http://www8.garmin.com/support/outofwarranty.html Does anyone know if you buy the refurb model will Garmin transfer the lifetime map upgrades over to it? This for me is going to be the determining factor. By the way the refurb now has a 90 day warranty.

    As for the digitizer screen, so this is the guy to buy from for the correct size: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190417956530&ssPageName=ADME:X:RTQ:US:1123

    Did the screen have the necessary adhesives on it to mount it to the frame? If not what should you use? Any one know how long it would take to get this part to the US?

    Thanks!!!!

    >Does anyone know if you buy the refurb model will Garmin transfer the lifetime map upgrades over to it?
    Don't know. Call Garmin and wait on hold for 45 minutes, and then report back to us.

    >As for the digitizer screen, so this is the guy to buy from for the correct size:
    The "mingxing200808" link on eBay worked for me.

    > Did the screen have the necessary adhesives on it to mount it to the frame?
    Mine was in the frame already. If you read the first two tutorials, others have indicated that their digitizers had adhesive on the digitizer, and you have one shot at positioning it correctly.

    >Any one know how long it would take to get this part to the US?
    He quotes 2-3 weeks. My second one got here in about two weeks.

    Looking at these links previously posted

    http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190417956530&ssPageName=ADME:X:RTQ:US:1123

    That one looks like the wrong size screen and he has them "on sale". This one has the correct sized screen...

    http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190451949930



    I have had a few instances where the screen locked up. Turned it off then back on and no problems. Yesterday I went to scroll the map and it wouldn't scroll. To make a long story short it seems like the unit is locked up. After messing with it for awhile I got to the "where to & view map" screen. If I push hard the buttons change color like they are being pressed but nothing happens. I tried to reboot and am now stuck on the "select a locale" screen.

    Tried the on button and the + button...no good, tried the on button and holding the lower right side of the screen, no good. Also took the battery out for a minute, then over night. Still no go.
    Got on Garmins website and found an update for the software. Great, maybe this will fix it. Nope! Supposedly took the software update but who knows...
    So I'm guessing I need a new touch screen too?
    Thought I'd get more than 15 months use out of something that cost this much...

    That sure doesn't seem to be a screen problem to me.:scratch


    Update: Garmin will transfer the lifetime map update to the refurb model.

    Also for a $150 deposit, Garmin will ship you the refurb model before receiving the defective one back. It only took 2 days to get it!!:thumb

    Yeah, it's got me scratching my head too. Kind of at a loss for what to do. Don't really want to spend $150 right now.
    Anyone else seen this happen before?

    Had mine three years and screen locked up. Went thru all the on line updates twice and gave in to the 150 fee. Still cheapest way outbut thinking of switching to something else anyway. Ideas? I like off road and do lots but gotta pound pavement to get there.

    My digitizer started getting weird a couple months ago and I finally got around to replacing it. I've had the 550 about three years. I do a lot of finger dragging on the map, so that probably accelerated the wear. I should try to use Mapsource more to plan routes.

    I got the part from Yang Lin Sen, Espeed Logistics, Hong Kong via eBay. It is slightly smaller than the original digitizer, but it still fit within the area of the gasket so I went ahead with it. It did have the adhesive on the back, but I had to peel off the plastic cover which wasn't immediately obvious.

    Hasn't been road tested, but it worked immediately definitely fixed the problem.

    The replacement was a little easier than I thought it would be. You will need sharp near-vision and a steady hand. I think the main tips are:
    1) Carefully flip up the little red tab to remove the ribbon cables
    2) Use an exacto knife or something very slender to separate the old digitizer from the LCD screen, but be careful not to cut the LCD screen.
    3) If the new digitizer is a little smaller than the old one then it's crucial to get it centered or it won't fit within the area of the gasket
    4) check and double-check that the screen gasket is seated in it's groove before you tighten down the screws...you don't want to score that and mess up the seal

    Thanks to the folks to posted photos and tips before me :thumb

    I just received and installed my new digitizer from the same supplier (xingming200808). I ordered the digitizer, was billed $30., and got one already with the metallic frame, so I only needed to fit it in after I removed the old one. Many thanks to all the good guys in this thread. I might have saved myself some money I intended for the 660, but I'll wait until I get to use the Zumo on my bike tomorrow to find out if it won't go bonkers on the road.

    On a sad note, I just noticed that my on/off button had a tear on one side. :cry I put some glue around it from the inside, tried pressing the button very gently and it turned on. I hope it holds. Still I dread to ride with it in the rain.:becca

    I replaced the digitizer....the smaller one from the e-bay seller with no problems. Also, the buttons...at least three on my 550 broke around the edges and one fell out. The solution is to buy a dummy display case that is used in stores. It has all the case parts including the gold plated connector on the bottom...just no electronics. You transfer your electronics and battery into the new case which requires soldering three battery wires and one antenna coax wire. Touch screen replacement is as covered in prior posts. Result...almost a new unit. :clap

    I ordered my "dummy" case from Darrel at www.tvnav.com - 785-625-3546 several months ago. As I recall, the case was 25 bucks or so. He may still have them. :wink:

    Good idea! My unit was the display model from Crutchfield in Harrisonburg Va. No dummy cases there.

    Hi, after replacing the screen my Zumo leaks. Does anyone have a solution for this? Can I use silicone to seal the screen and case? Thanks, George

    Silicone is a last resort but is effective, use sparingly.

    Q: Is the replacement screen EXACTLY the same size as the original?
    If so, you may have the front seal twisted or out of its channel.
    If the screen is undersized then you will probably need silicone to seal unless the screen is exactly centered which is difficult to do.

    Note: If your Zumo leaked be sure to dry thoroughly (use a hairdryer on low heat for 3 or 4 hours) as the water creeps up the back of the main circuit board and the board will corrode over a couple days if voltage is present on the board. The unit will then be junk.

    Thanks guys. Found this thread and ordered a new digitizer, pronto. My 550 also took a crap 2-3 years into service. Can't wait to get my parts from Hong Chong and get back to Zu-min'.....

    The risk here is that you F up the procedures. Like maybe the ribbon cable doesn't connect a easily as youd expect and you end up breaking stuff. Then you're screwed because no Garmin won't warranty it, at all... And you get stuck with an oversized $700 kickstand puck. Ask me how I know.

    I feel your pain brother. I decided to have Garmin send me a refurb 550 for $150.00 and your post is confirmation that its the right thing for me. A guaranteed working gps and warranty for 3 months is worth it for me. If I were you I would talk to Garmin anyway........maybe they can work something out for you.

    Take heart though. Do it yourselfers like yourself are not always successful when we dive into uncharted waters. I'll bet you've saved far more than you lost. Besides you know that you really wanted a 665 anyway.
