#1 of 15 Electrical Gremlins by kygoat Oct 11, 2006 (7:40 am)
I’m experiencing serious electrical issues. Occasionally all of the gauge needles and cluster lights will go crazy for a second or two. The passenger window will then no longer operate from the driver’s side control and “one-press” up and down stops working.   Most annoying is that all of my radio stations reset back to default and with Sirrus radio that is 36 presets lost.   This morning the only way to start my CX-7 was to use the secret key-fob real key.   I have nearly all options. Anyone else seen these issues?

Replying to: kygoat (Oct 11, 2006 7:40 am) You're the first to report - congratulations! Don't you feel good about that?   Pickin' on ya. Seriously, a trip to the service department is in order. I've sneakin suspicion that the security system has gone haywire, but that's only a guess.   If you find out what's wrong, would you care to post back here again?   Vince.

Replying to: vbbuilt (Oct 11, 2006 4:09 pm) In the shop today. I agree it seems to be with the keyless security system. I think it gets confused and reboots all systems to recover.   I did tell the dealer "I don't want it back until you recreate the problem" I'll see if that will fly or not.

#5 of 15 Clock Settings by nmk Oct 29, 2006 (7:18 pm)
Manual states that clock will change automatically with navigations system. Ain't true. Anyone have any ideas on how to change the clock setting?   Dart Vader CX-7 AWD & Nav system aka NMK Replies to this message: astegman (Oct 30, 2006 5:34 am)

Replying to: nmk (Oct 29, 2006 7:18 pm) Go into the Nav system and choose user setup. You should be able to find your way to the clock settings from there.
#7 of 15 Clock Setup with Navigation system by 022540 Nov 09, 2006 (5:12 pm)
I was waiting for auto time change with Navigation system. It even states that in the manual.   Go into the Navigation system, configure.   there is a clock setting. press buttons accordingly.   It took a little while, but it turns out to be pretty simple.   Good Luck!!!!!!

Replying to: kygoat (Oct 11, 2006 7:40 am) I'm having Electrical Gremlins also.   My radio lights flicker. It's JUST the buttons for the radio, not the upper dash display or the gauges or headlights... after I've been driving the car a while (at least 20 minutes), I assume when it's gotten good and warm, the radio button lights start to flicker. Nav screen and all other lighting appears to be fine.   Anyone else have this issue? What fixed it? I have the latest PCM Flash (they did it today). Dealer could not replicate the problem (probably because they weren't driving it for more than 20/30 minutes LOL).   Help?

Replying to: kygoat (Oct 11, 2006 7:40 am) I just got a CX-& Sport last week, pretty basic. Power seat, Bose package, sunroof. Saturaday my daughter notice the clock/radio display on the upper dash was not working. Also tne keyless entry would not work, nor the power door locks. The TCS light was flashing and a light/picture of a car with zig zag lines behind it stayed on. Later that night, the stereo and clock worked but the keyless entry still did not work. The stereo had erased its memory and I had to reprogram it, also the TCS light stopped flashing after a short drive. This morning, everything worked perfectly. Then again, this afternoon, the whole thing repeated plus the interior light do not work.   Heck, the thing only has 100 miles on it and this is what I get. My only saving grace is that it is a company car and I don't have to pay for it. Replies to this message: kbramstedt (Apr 30, 2007 10:34 pm)

Replying to: kbramstedt (Apr 29, 2007 8:44 pm) I took it to the dealer I bought it from. They ffound a loose fuse. It was located in the engine compartment fuse panel. It is a fuse the dealer installs when they do a pre-delivery inspection, and they did not push it is all the way. They said some of the electrical problems people here are experiencing might be due to the dealers not inspecting the fuses before delivery. This is the closest dealership to the Mazda USA office in Irvine, CA.
