It\'s related in that your \"entertainment system\" is failing.

Well, *that\'s* a stupid implementation decision!
occasionally I\'d get an error message when car first started so radio
first tries to read the map. I would either stop and start the car, or
later I realized I could eject the DVD and reinsert it and it always
worked the 2nd time. (There is a separate CD drive for playing music.)
Bought a DVD cleaning DVD, which is a disk with a brush! Used 2 or 3
times. Didn\'t help.
Changed from the 2005 edition of the map, that came with the car when
new, to the 2008 edition, the last year they made one. Didn\'t help.
Both map DVDs look pristine. No fingerprints, not even old ones that
have been wiped away.

In the last month, problem\'s gotten more frequent, but still worked the
2nd time every time. Yesterday, didn\'t work until the 3rd time. And
today, right after I bought tires for a car trip tomorrow, wouldn\'t work
right at all.
I restarted the map, and the map restarted itself 2 or 3 times** for
each time I restarted, and never completely displayed the map, and
always insufficent for moving my location while I drive***.
A couple strange things, never happened before today: 1) Start of the
day, changing stations, which is usually instantaneous, took 5 or 10
seconds every time. Changing volume, for which there is a knob
(although it\'s not a direct rheostat control) also took 5 or 10 seconds.
Changing from FM band 1 to 2 (6 memories each) also took 5 or 10
seconds. Saving presets took 5 or 10 seconds. This delay phenomenon
never happened before and I don\'t see how it\'s related to not reading
the map DVD, but otoh, it\'s not a coincidence, is it? (Once the radio
was on a station, the radio worked fine.)

2) Sometimes**** much of the map showed, but a quadrilateral

blank. But driving didn\'t move the map. ****Or maybe all the time. Sun
was very bright.

Is there a better way to clean the head? A more expensive DVD head
cleaning CD? Maybe the one I bought didn\'t know how to work because it
was not a general purpose DVD or CD slot, but a dedicated map DVD??? So
the radio software was incompatible with, or didn\'t try to execute, the
cleaning DVD software. Maybe NO cleaning CD knows how to work with a
Map DVD slot?

Or should I disassemble the radio and clean the head directly?
(Previous car had a 5-CD changer that broke. Major effort just to get
the CDs out, had to destroy the changer mechanism. Never did see the
head.)
Should I try cleaning the head again, even if it didn\'t seem to help the
first few times, because clearly now it\'s worse, so maybe even a partial
cleaning will be enough?
Should I use a liquid or solvent on the brush. I think it didn\'t say to
and I didn\'t last time.
CD/DVD shouldn\'t need to be cleaned -- unless you\'ve got toddlers
handling them with sticky hands.
There are junkyard radios, but would they be fully tested? How can they
fully test a map that is meant to move when the junkyard car has no
engine or tires? And no GPS antennna. I presume the radio is tested,
but seriously, do they, can they test the map?
***I\'ve only used navigation twice in 5 years, once in the dark in
Charlston, S. Carolina, but I use location all the time.
**Convertible, top down, lots of sun, so hard to see the screen, but I
could see between attempts, in the center of the screen was a little
clock symbol, and the time on the clock was different each time!!!
Curious if there\'s a pattern, but had to pay attention to the road.
BTW, I just bought two new used tires today, so that I could go on a
4-day car trip tomorrow, and as I was leaving the tire place, or maybe
first thing this morning, that\'s when the map broke! I love my map,
especially when wandering around places I\'ve never been before, which
was the exact plan for the next 4 days. What irony!

One poster on the web thinks that having a map DVD in one\'s car for
years damages the DVD. Do you think that\'s true? I park outside and
it goes from 10F in the winter to 97 in the summer, but usually under
90. The car is white and the top is tan, but it does get several
degrees hotter in the car than outside. I think I bougbt the DVD new 4
yars ago, even though it was made in 2008.

Why is it too late? Is the DVD stuck inside the unit somehow? If not,
I was thinking that, if the current problem is that age or heat had
damaged the DVD already. But last night I went out and tried it
somemore and the GPS works, it just keeps flashing that message ever 3
or 4 minutes, but in between it does keep track of where I am and what
direction I\'m going. In fact that clock I post about that changed time
was actually the arrow showing which direction the car was pointed.
