Wow... three problems all of a sudden

...and I'm not sure what forum to stick with, so I'll do it here...

I've been real quiet about the check engine light "issue" for fear of jinxing myself (LOL) -- oh well, so much for that... Engine light popped on tonight. I checked the gas cap and will do so again tomorrow, and then call the dealership.

The other problem is the radio. Sunday I stated getting "Antenna Failure" messages on my nav display (meaning the satellite radio antenna). It's been deep-freeze cold here so the first day I chalked it up to ice... but now it's continued off and on since then.

And tonight, when I got in the car, the navigation display is dimmer than it should be. At first I thought it was my eyes needing to adjust until my daughter said it looked "faded" to her. It's not a huge difference, but suddenly I feel like I'm squinting to see it. This is at night, with the headlights on... just so no one thinks I mean it's during an overcast day (where the headlights have kicked on and made everything dim).

It also looked like one side of the nav screen (right side) is dimmer than the other.

Anyone else have similar problems?
 
Could be, and I hope not because electrical problems (short of a bad battery) can be a b**** to figure out. If you remember, I also had problems intitially with the radio-button-lights flickering and the cause was never determined. I ended up figuring out myself that it had to do with the dimmer dial (even though none of my other gauge lights were flickering).

Last time I talked with the dealership about it (in December) the service manager told me to stay in touch with him if I had more issues... he said he had "heard" there were "issues" with the Bose/Tech Package system, but wasn't more specific than that.

:( I am so not happy.
 
If it's ridiculously cold, the fluorescent lights used to backlight the LCD might take some time to warm up.
 
It may cold related. I have noticed that under very cold conditions (below freezing) that when I first start my vehicle and drive - there have been a few times that the nav was WAY-OFF... not even close. wrong direction, wrong position, etc... and after about 5-10 miles, it corrects itself.

And the same with the LCD display - it DOES take time for it to "warm-up" under very cold conditions - it should be back to normal once the interior temperature gets up there for 10-15 minutes.

I know they try their best to prepare for these conditions, but there's only so much you can do with certain technologies within a budget.
 
Well it wasn't ridiculous cold. About 20 degrees.

I warmed up the car for five minutes before even getting in, and then was driving/in the car for about 30 minutes. That should have been plenty of time for the nav display to "warm up". It also doesn't explain the "Antenna Fail" messages (and lack of Satellite reception).
 
Well, I would hope that TO THE CAR neither 45 nor 20 degrees would be "ridiculously cold".

Talk to my dealer. I'm going to drop the car off Friday. They aren't going to look at the radio yet because I'm trying to get some resolution from Mazda corporate considering my overall disatisfaction and problems with the unit. They'll get the check engine light thing under control and then we'll see what happens with the radio -- because the only thing the dealer can do is replace it.
 
Update

Here's the update.

I went and dropped my CX-7 off last night at the dealer. The Service Manager sat in my car with me for a while and agree that the navigation display was dim and he felt the same as I... like he wanted to squint.

We went and sat in another CX-7 with Tech Package on the lot to compare. It was THE SAME... actually a little worse... and we determined that indeed, when it's really cold out, the screen needs to "warm up" significantly before it improves (you were right Kansei).

They kept the car all day today for the Check Engine Light and "Antenna Fail" problem.

My antenna needs to be replaced. It's ordered and will come in next week.
I'll bring the car in next week for the Antenna... IF I decide not to pull the whole radio out. I already told the Service Manager I may just come pick up the Antenna rather than have them install it (if I do indeed decide to go aftermarket). Otherwise, car will go back in next week so they can replace the Antenna.

As for the CEL... it was the P2006 code, meaning the IMRC Valve. There are two ways to go... dealers have been instructed to perform a fix on it, rather than replace the part, because Mazda can't produce them fast enough (I've heard this elsewhere too). Service Manager told me that he HAS to do the fix first... Mazda is telling them they cannot replace it unless the fix fails.

He said they did the fix and the car is running great - and no more codes. They also gave me a new PCM update... no details on the update though.
 
Re: Navigation Display

And here I thought it was my Senior Silver Fox eyes that were failing me.
Happy to say it seems that it is the cold causing the problem.

I don't have enough experience with double-din nav displays to know, but it seems KINDA lame to me that the cold effects the brightness so much.

I also found out today who makes the Head Unit in the Tech Package. Straight from Mazda's mouth, it's a Sanyo.
 
did you have the SSP69 recall done yet? if not this is why you're getting those error messages
 
ANY LCD panel is going to be slow to react/dimmer than normal in cold weather (anything below 35-40 degrees is cold when talking about any type of display) the induvidual cells that control pixel color/change need to be slightly warm to help with the change otherwise they cannot react fast enough. Also electrical currents move slower in colder environments which is why flourescent lighting takes a bit to warm up and reach max light output.

a TV is going to do the same thing, its not limited to a nav system (and most television technologies can be even worse, sometimes cracking due to the quick change in temperature from turning off to on in that type of weather).

If it makes you feel better, in the GT mazda 6s you actually have to wait for the car to warm up before you can see the automatic climate control display. It actually WONT turn on for 5-10 minutes...
 
Wow, you could have just linked to your own post as easily as the search page :(

Either way, it doesn't apply to me. You say right in your own post "2007 CX-7 WITHOUT NAVIGATION".

I read about the problems people were having back before I bought the car. If I remember correctly they weren't getting "ANTENNA FAIL" messages, it would just hang on "Acquiring Signal" and never get a signal. That would have to do with Sirius and the unit programming. My problem is a bad antenna.

Hi Rabbit, was wondering has the problem with the IMRC valve on your CX7 been fixed? No more CEL? I also have the same cause for my CEL and its still at the dealership waiting for the parts over the weekend..
 
Papaalex,

So far so good... but it's only been a week since they did the fix (it was done on 2/9/07).
