Check to make sure you don't have the batt+ wire and switched 12v wire mixed up. batt+ is usually yellow or orange while the switched 12v wire is usually red, consult the manual or look on the unit itself. there should be a wire color description there. batt+ is what you want 12v running to all the time to keep the settings. switched 12v is the one that turns the unit on when the key is turned on. the unit will still operate if the 2 are backwards but like you said it will clear the memory every time you shut it off because your cutting power to the batt+ wire thus resetting the unit.

Your best would be to buy a harness adapter to connect the new deck through the adapter into the existing OEM wire harness connector. It makes things so much easier and more reliable.

Make sure the yellow wire is connected to a source that still has voltage when the key is turned off. The yellow wire controls the memory of the deck.

Bmw 318i se auto clock reset problem?


a little more information would be nice but im going to make a guess
you installed a new deck in the car, now every time you turn the car off the clock resets?
if thats correct.. the deck will have 2 power inputs, one that turns the radio off when it does not have a power signal, the other that should have a constant voltage to maintain the stereo memory, now if I'm correct you have either the 2 wired opposite to how they should be or both wired to something like the ignition wire, and it is acting like the battery has been removed every time you turn off the car, which means you need to check your stereo wiring.
if this is incorrect please leave some more info telling everyone when the clock is automatically reseting.

Deck turns off when i hit a bump in my car


A couple things...but the deck must come out to check. (assuming this is a 12v N.American car) If you cannot remove or you dont know how - take it to a car stero shop. Electrical fires are nasty!
  1. Make sure there are no open wires and connections are tight and taped (badly crimped connectors will hide loose connections)
  2. Make sure the deck is supported in the back-it should not wiggle around.
  3. There should be a wire firmly connected to the chassis of the car and the back chassis of the deck - Please do not drill into the deck - use an existing bolt !

My memory wont work after 5 minutes or truck shut off but will after a minute or less


Are you positive that the yellow (memory wire) from the Panasonic (use a test lamp or meter) is continuing to get power after you turn off the truck and wait 5 minutes? And the Black ground is proper ... If so then it will likely cost more to repair the deck than replace it. Or you could wire the red wire to the same place the yellow wire is wired to ... then just remember to shut it off when you leave the car (or suffer a dead battery 12 hours later) ... and it won't cost more that the cost of a couple crimp connectors to do that ... the frugal way.

Constant Power wire draining battery HELP!


Okay, I think I have it. The red and yellow wire into the deck need to be connected to two different power sources.

The red wire should only be hot when the accessory switch is on. The yellow wire is for constant power to maintain memory in the deck.

Connect the red wire to a source which is only hot when the ignition switch is in accessory position -- that should solve the problem.

You might have...my best bet would be on the memory wire not being shot solid 12 volts. There are 2 wires meant for 12 volts the red one which has 12 volts on it when the car is turned on only. And the yellow wire which should be at 12 volts all the time. If you have power at the Yellow wire at all times then you might have a deeper issue. I hope this will fix it.
