I just recently got an automatic car starter installed, and since I have had a few problems with my F90bt.

I only had this nav unit for a few weeks, so I can't necessarily say the automatic car starter has anything to do with it-- that's why I'm posting here.

What happens is after I get in my car(after it has been started remotely), I put my key in and turn it to the on position, and I'm able to drive away. What I've had happen(not everytime too, this only happened 2 or 3 times out of the 10 or so times I've started the car remotely) is that my touch screen is unresponsive. Nothing will react to my touch. I AM able to press the menu and map buttons, but when I see the warning message pop up, I cannot procede further.

I don't beleive this has happened if I start my car normally, but again I'm not sure if this even has anything to do with a remote starter. I know they do alter wires that start and power the car, and perhaps a few other wires.

The only way around this is to turn my key while I am driving as if I was starting it again-- just quickly, so that it will repower the devices attached to my car.

Does anyone with experience in this area know if it's fathomable that a car starter could have caused this problem? Do I have a problem with my unit in general? Or is this a known bug with this device?

Thanks.

False. No wires should ever be "altered". At most, wires should be teed into, with the exception of the starter wire which may be CUT for starter-kill/anti-grind. All the remote starter does is hotwire the vehicle, it duplicates exactly what would happen as though you had turned the key.

I have had my screen go unresponsive too, the only fix I was able to find was to reboot (cut and restore accessory power). Keep in mind, it is a computer on the inside, I'm sure we've all had to reboot our desktop computers before.

Exactly what I had thought. Computers is my field and believe me, my first thought was---- F&*@$ing Windows.

I'm going to keep monitoring it, but it really has been happening an unacceptable amount of times. This would mean that unless I have a defective unit, everyone will be experiencing the same thing? Is this the case?

F&*@$ing Windows.

Exactly.

I think in the 3ish months that I have had my F90 it has had that issue maybe 5 times, uncommon to say the least but still inconvenient. Just one of those things.

Gotcha-- thanks.

Other people having this issue as well? Just trying to clear my mind that I have a problem, and this is an issue with the unit itself.

with a viper 500esp this problem only happened once... and I remote start the car every day

It's just been very frequently for me lately. I have heavily modded my unit, so I hope it's not something that I've done.

Though, a touch screen being unresponsive is a bit odd. Like I said, the map and menu buttons still work... so it makes me think it has more to do with the touch screen.

But again, I would assume the touch-screen is just like a typical hardware device that is connected and loaded by Windows.

Noticed something today. Remote started my car got in and pressed ok on the dumb caution message and nothing happened on the touchscreen.

I stepped on my brake pedal and then my touchscreen started working. I think it has something to do with the ground.

Aha.

I know that the brake pedal is wired in a way so that if the key is not in the ignition and you press the brake, the car will shut off. So that probably somehow ties into the nav unit?

We'll need to test this out to narrow it down.

The brake wire is used to shut down the car if somebody gets in while it is running, and they try to drive away without the key in the ignition. Also, when the key is inserted into the ignition and you hit the brake, it returns control back to the car from the remote starter. Nothing special, unless you have a car with a smart key (push button start) and then the brake wire must be cut and passed through a relay.

All remote starters are required to have the brake pedal hooked up. The brake wire is in no way related to the Nav unit.

jrdiesel, correct me if I'm wrong on this, but the only way I can see the remote starter interfering is if they tapped into the wrong accessory wire.

Depending on your car, you may have 1 or 2 accessory wires in the ignition harness. Tapping into the wrong one, or failing to use both can result in some accessories not turning on when you remote start the car, such as the heater. It doesn't seem likely however, as the unit does in fact turn on.

100% correct.

If a 2nd ACC wire IS needed on the remote start, it WILL shut down during the crank cycle, maybe this is disrupting the boot sequence of the unit, and in turn affecting the touch screen program. In that case, whichever ACC wire is energizing the radio needs to be set as IGNITION, or "ground while running" or "status" (depending on the make of the starter).

I have seen up to 3 ACC wires for one vehicle. Dakota, if memory serves...

with my f900bt deck, 6 out of 10 times no response at all when pressing the screen...

OK. Weapon, and Bitman, what year make and model is your car?

2008 Hyundai Tiburon.

Here's what I would do. Get a test light, and find the ignition harness. It will be the one with all the wires tapped into it behind the shield or clamshell. Find a wire in that harness that hasn't been touched. When you probe it, it will turn on, cut power when when you crank, will turn back on after the car is started. If you find a wire that does that, and it hasn't been tapped into, chances are that's your accessory 2 if you have one. Take the wire off the pink wire (ignition 2) and tap it into that acc 2 wire with it and see how the unit reacts. If it doesn't change anything, just undo any changes.

Careful disconnecting that wire, in some cases one ignition wire runs the fuel pump and the other energizes the coils, and one of them may also be required to operate the fan. Both ignitions may be required still.

My program doesn't have a 2008 Tiburon listed, but for 2007 it doesn't show a 2nd Ignition either.

Very much appreciate the information. However, that all sounds a bit scary to me. I had someone else do the work for me to put this remote starter in. However, they might actually have to do some additional work with it in the future, so if there is something specific I need to have them change, let me know.

What exactly do you think is happening? Is it that the Navi is wired into the brake somehow, instead of being used on a separate wire?

No, the unit is wired fine. That's not a question at all. The possibility I brought up and asked Diesel, is whether the power wires for the remote start were properly wired. What he was saying about the brake is every remote start has an anti-theft feature that gets wired to the brake switch, that way if you start your car, nobody can just hop in while it's running and take off. When you remote start the car, turn the key and press on the brake pedal, you are disengaging the remote start and the car is now running on its own.

Ah yes. I do know about that-- the guy who installed my remote starter went over that with me, and I tested it out. My car shut off when I pressed the brake before putting my key in the ignition.

I also see the parking lights go off when I press the brake after properly inserting my key into the ignition-- showing that the car has switched over to running off the key.

According to blackh, the touchscreen was unresponsive to him before he pressed the brake, but it worked afterwards. When I have noticed the screen not responding, it is after I am already driving(though I didn't attempt to touch it until I was already driving).

See that's what makes this problem so complicated. You, Blackh, and Bitman have reported this problem as far as I know. BlackH gets control after pressing the break, Bitman gets control 6 out of 10 times, and you never do. It's so inconsistent.

No, sorry if I misled you. It's only happened to me a few times-- not always. I would agree with the 6 out of 10 times. It hasn't happened to me in a few days as of this moment.

Hmm, you don't have an accessory 2 either.

Howbout this. Try not using the remote start for a few days, see how the unit works. If it works perfectly, I'm completely 100% stumped. The autostart, may somehow be interfering with the systems performance, but I honestly cannot see how. If it still performs the same, I'd have to say it's a defective unit.

Prior to installing my autostart, I only saw this problem happen once, but it stopped responding after I had been driving for awhile.

Since installing the starter, I've seen it happen when I first start driving.
