    California changed the law on mounting a GPS unit on your windshield,
    but the law still seems complicated and limits your options.

    (12) A portable Global Positioning System (GPS), which may be mounted
    in a seven-inch square in the lower corner of the windshield farthest
    removed from the driver or in a five-inch square in the lower corner
    of the windshield nearest to the driver and outside of an airbag
    deployment zone, if the system is used only for door-to-door
    navigation while the motor vehicle is being operated.

    How many of you use a GPS device and mount it using a suction-cup
    windshield mount? Where on the windshield do you mount your unit?
    Have you ever been warned or fined by police? Thanks

  2. Doesn't seem overly complicated to me. It's just saying it has to be
    down in the corner, instead of in the middle of everything like some
    idjits do it. Of course, I don't have one, mine are all built in or
    in my phone.

    Even with all the regulations, I still wind up at stoplights where I
    can't see the light from a normal seating position. I can think of
    one left turn lane where there is a sign for the other direction
    traffic that blocks the view of the signal. (Where the black SUV is,
    if I got the link right:,235.18,,0,0

  3. What does that last clause mean? That you can only mount the device there
    while you're obeying turn-by-turn directions from the device, but can't
    mount it there if you simply want to be able to look at a map and find your
    own way?

  4. Hi,

    The wording says to me that only large delivery trucks will meet the
    requirements. FedX, UPS, USPS ...

    I have my GPS mounted below the windshield and it works well there. UMMV
    (Delorme PN-60)

    shows the gripper mount, I found a different base that the gripper mates
    with and my Van Conversion shop mounted it to a air duct.

  5. After early experiments with suction cup windshield mounts I now
    always mount the device, typically a smartphone, in a holder
    that hooks on to an air vent. This has a whole range of
    advantages, so much so that attaching one to the windshield
    seems like a truly bad idea.

    Would that not be allowed in California?

  6. It's not complicated at all. You're allowed to mount your GPS on the lower
    corner of your windshield (either side).

    Of course if you're a solo driver, it doesn't really make sense to mount it
    on the lower corner of the passenger side.

    And the text says that a device is allowed in the lower left corner of
    the windshield, given it is completely within a 5 inch range of that
    corner? With other words, many combinations of flat-angled windshields
    and devices are not legal, because even these are less than 5 inch
    wide they will not fit in that range as the windshield is monuted flat
    and the real corner can't be used.

    On the other side: I was in California often enough and never had any
    trouble with that.

    Who would seriously be stupid enough to mount a GPS in the middle of the windshield.

  9. Simple, just mount it on the outside.

  11. [clipped long link because my newsreader semms to have mangled it :)]
    Suggestion: for long links, use or

    The result is a couple of dozen characters long with no more worries.
    The sites are easy to use.

    Example: here's the tinyURL of your long link:

    343 characters reduced to 26 and no clipping...

  12. I read it as "while the motor vehicle is being operated" don't use it
    for anything other than "door-to-door navigation".

    And while the motor vehicle is not being operated, no restrictions.
    Gene E. Bloch, Apr 19, 2012
  13. The only restrictions are on windshield mounting. Non-windshield mounts
    are not restricted.
    Gene E. Bloch, Apr 19, 2012
  14. Best idea yet :)

    I use a rubberized pad with a GPS mount on it. I set it on top of the
    dashboard to the right of the steering wheel, where it's easy to see
    and doesn't block anything. It's legal, but it does vibrate a little.

  15. Some places block shorteners. Some funny people put in goatse.

  16. Example: here's the tinyURL of your long link:

    No one in his right mind trusts URL shorteners, no matter who sent them.
    John David Galt, Apr 21, 2012
  17. You needn't trust - it's trivially easy to verify.

    Of course, what you get is an expanded URL, just like the one you would
    have seen in the absence of a tiny URL. But you still have to figure
    out whether to trust the long version.

    Basically, your remark was silly...
    Gene E. Bloch, Apr 21, 2012
  18. That's nice, but then everybody would have to know every such
    preview trick for every URL shortener system in existence.

    I agree that they should not be used at all.

    At least with tinyurl, you can go to the site ( and
    tell it that you always want to use preview.
    Joe Makowiec, Apr 21, 2012
  20. Don't forget what I said upthread: even a full URL can lead to bad
    things :)

    Sometimes I post both the tinyURL and the full URL, sometimes I use the
    preview form, and sometimes I choose not to worry about the people who
    can't or won't trust me.
