On www.nitroforumz.com I asked a question about a problem I'm having with my
navigation system (Dodge Nitro/MyGIG). Below is an extract from this forum
showing the type of problem I'm having. I've had the wiring and antenna
checked and the dealer couldn't find anything wrong. The dealer claims they
called audio engineering and were told that this is a known problem and that
there is currently no fix. Any thoughts? Has anyone else had this problem?
Was it fixed? Thanks.

So we went to a family wedding in Oshawa, Ontario this past weekend. I knew
where I was going without the NAV but kept the map display on just to see
what would happen. As I was driving up I-94 in Michigan, generally speaking
it was working but as I got close to Port Huron it started 'wandering'. When
I crossed into Ontario heading east the vehicle icon was heading in a
westerly direction and showed me out in Lake Huron. 26 km into Ontario,
wham, the display came back and showed me exactly where I was. I likened it
to the system not being able to get a signal out in the lake, looked for a
new signal and put me back on track. I'm sure that's not what happened but
that's what it seemed like. It worked fine until I got just west of Toronto
and then the icon traveled in a circle. This was near the Toronto airport
and it had me circling around on the map as if I was circling the airport.
When I got to my destination the Nav showed I was still 56 miles away from
it!
The next day I ran some errands in the Oshawa area and it worked fine. Later
however, I entered the address of where the kids were to be baby-sat and I
followed the NAV directions to the house. But, the house address didn't
exist on the street I was on because the Navigator was telling me to turn
where I shouldn't be turning. Knowing it didn't always work you would think
I would have double checked the street signs but no! We were pressed for
time, I was rushing and careless. Turns out I was 2 blocks away. Needless to
say, by the time, I re-oriented myself, found out how to get to where I was
supposed to be, etc. we were late for the wedding. But, we did get there in
time for the I do's. And it was a great party afterward.
