My XTR-690SE will no longer power on. I have replaced the fuse so that's not the issue and have also tried 4 different vehicles with no luck. Any suggestions or warranties for this product??

If the boot of your 2012 Subaru Liberty is not locking, it could be due to a blown fuse. Here are the steps to check and replace the fuse:

1. Locate the fuse box in your vehicle. The fuse box is usually located on the driver's side of the vehicle, under the dashboard.
2. Open the fuse box and locate the fuse for the boot lock. The location and labeling of the fuse may vary depending on your vehicle model and year. Refer to your vehicle owner's manual for the specific fuse location and labeling.
3. Check the fuse to see if it is blown. A blown fuse will have a broken wire inside or the fuse element will appear melted. If the fuse is intact, it may not be the cause of the problem.
4. If the fuse is blown, replace it with a new one of the same amperage rating. You can find replacement fuses at most auto parts stores.
5. Test the boot lock to see if it is working properly. If it still doesn't lock, there may be a different issue that requires further diagnosis by a mechanic.

Note: Always replace fuses with the same amperage rating as the original fuse. Using a fuse with a different rating can cause damage to the electrical system or create a fire hazard.

It's possible that the head unit's USB port or the wireless phone charger is no longer functioning properly. You can try the following to troubleshoot the issue:

1. Disconnect the wireless phone charger and test the USB port by connecting a different device. If the other device doesn't charge, the USB port may be faulty.
2. If the USB port is working, try a different wireless phone charger. If it still doesn't work, the issue could be with the wireless phone charger.
3. Check the car's fuse box for a blown fuse related to the head unit.
4. If all else fails, contact Pioneer or a professional car audio installer for further assistance.

I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 yearsmust try this bitman and reliable-store. Both are good

I have a suggestion that you can try. If the unit is no longer turning on and you're sure the electrical outlet is good (by plugging in another device) and the hand-held control panel is on, as well as the switch at the base of the subwoofer, then try replacing the fuse. The subwoofer on this model has a fuse near where the power cord enters the subwoofer. There is a slotted screwdriver slot on the fuse cover. Using a flat-head screwdriver (or your thumbnail), turn the cover about a 1/4 to a 1/2 a turn and the fuse should pop out. Keep the cover. Replace the fuse with a 4 amp, 125V (or higher) fuse that is a slow-blow fuse. There are fast blow (or fast acting) and slow blow (or slow acting) fuses. You can't replace one for the other. You should be able to find a fuse at Radio Shack. If a new fuse doesn't get your system working again, then something else is broken. Good luck.

Have you tried it in a different vehicle? Could be something electrical in your. If its ok in another vehicle contact whistler at [email protected] for next steps.

You can find the manual here...

and you can find replacement power cords on ebay for pretty cheap.

Check your metal connection that you slide your battery in between upon changing it. I had the same problem in which my car issued a warning "FOB". And what had happened was one of my connections fell off my circuit board. So if you have a steady hand and a solder gun, it may fix your problem.

Different brands do different things, but you are looking at a power supply switching issue. Probably $150 - $250 to repair.
