    I'll take a look. Dealt with a lot of flex connectors, but this one has me stumped. Thanks.

    Hey, first thing I thought of, but no standalone GPS on this MK5. Went thru it on my MK2. In any event, the self installing driver package installs the GPS registry patch. I even disabled the Gobi card in the bios because it includes it's own GPS, just in case.

    Other than the touchscreen issue, this MK5 works great. Absolutely flies compared to my MK2. I specifically got the MK5 for it's Sata3 capability. The car diagnosis programs I use on it are disk intensive, especially during 20gb+ updates. Saves a lot of time.

    I think you may end up needing a new panel.

    Meanwhile check around the edge of the touch PAD. Could you have some gravel in there?

    Do you have a picture of the screen latch?

    If Windows [calibrate] doesn't "see the TSPCB then resetting the registry won't help.

    Yesterday I put a new panel in a CF-29. It was non-touch so I added a TSPCB. Put it together and nothing. The bios saw the TSPCB but nothing. Soooooo I put a different TSPCB in there and bingo. Apparently the bios sees the ground on the TSPCB and is happy.....sorta like the extra ground on a CF-29 GPS showing a GPS in bios......if that makes any sense.

    Did you do a battery pull reset?

    Yes, checked around the edges. Thought the bottom of the bezel might be bowed in slightly, but it wasn't the issue. Not touching the panel.

    I took some pictures, but none show that connector clearly. It's reassembled now.

    When you say battery pull reset, you mean the bios battery? I'm going to change out the wireless card anyway, so I'll pull it then.

    Is the TSPCB the PCB the ribbon from the touchscreen is plugged into?

    Both the bios and device manager see the touchscreen, and drivers show no issues. If I turn off the touchscreen in the bios, the two drivers for it in the Human Interface Devices entry in Device Manager disappear. Turn it back on, and they reappear.

    Thanks for your help.

    I usually just pull all power and hold the switch on. Cmos battery is left plugged in.

    On first boot after that set bios to defaults and save.

    And yes the screen plugs into TSPCB. The manual calls it TS PCB.

    Push on the brown slider to unlatch. The cable is taped with a black protective piece and probably a piece of Kapton tape under that.

    This is NOT the latch I remember....maybe that's on earlier CF-19.

    Images are from my MK6 dual touch.

    My brown connector doesn't have the black part in your picture. It appears to be all one piece. The ribbon cable is thick in the area where it plugs in. I was able to pull it out and reinstall it without too much problem.

    Battery pull and bias reset didn't fix it. Guess I'll order a new panel.

    The TS PCB that I was thinking of was on a MK2. On that unit the cable must be flipped. Typing on one now.

    G'luck.

    Here's a picture of the touchscreen connector that appears to have no release. Tried pushing, pulling, lifting, etc. The cable is just stiff enough to push in and out.

    Thanks to SHEEPMAN! for selling me the new touchscreen. Works great, and now it's fully functioning.

    I did end up with these two small spacers(?) that fell out, and I have no clue where they go. Can anyone help?

    Are these the things that hold the pen tight in the lid ?? Is your pen loose when you put it in the slot in the lid ? On my phone now and can't really see the pic too good. Same thing happened too me on my MK3.
