More likely "YES", you might lose radio memory.

I replaced my battery on a 2000 toyota tundra now it is slow to accelerate. What could be the problem

Could be that when you did the battery trade, memory settings in radio and computer were erased and now the car has to reconstruct what was lost for it to operate the way it did formerly. Did you use a memory saver when you did the swap? Possible that you inadvertently disconnected a wire or harness?

My vw Passat 16 plate infotainment doesn't appear to be working, I have lost all radio stations bar a couple, it won't save them anymore, when I save one and stop the car lock it and get back in everything...

It has lost battery power. It has 2 power sources. The battery is constant, no fuse. This is for the radio memory. The ignition is fused, it is the one that turns the radio on. You have to pull the radio plug and check for battery power. If it is there, you have an internal radio problem.

2000 Lincoln LS V8 radio doesn't play but has static. Replaced #18 fuse under dash and just took battery cables loose. Have not put cables back on yet

If you disconnected the battery, you should have lost the station memory. Are you sure its on a station now, and is the antenna connected ?

I was having this problem with the Honda radio and I have since replaced it with an after market one. I still have the problem with needing to disconnect the battery for the radio to work for a little...

a new radio?, or used, make and model # , must i guess?
all modes on the radio dead, AM/FM,CD/USB/IPOD jack
ALL, that be the first tests and if all bad that means you lost power.
does the radio scan? show signs its trying? when asked, LCD live? or dead. all i know is the word PROBLEM (vast possible)
did you ask the maker of said radio.
did you follow the new radio's instructions sheet.?

disconnecting the battery, wow !

the radios can have 3 or 4 power pins.
1: Radio power (head end power)
2: dial light (goes to car park dimmer)
3: some have a memory wire, if not connected all programming will be lost. this must go to HOT ALL TIMES line.
4: electric antenna, (it's an output but is power)]

and at least 1 good speaker connected.
and for AM/FM any test antenna or just a wire 12ft long works.
the radio can be bench tests.
1 battery 12v
1 radio
1 speak or 2.
1 antenna. now can test for days like this..... anyone.

I lost the battery connection while connecting new radio and cant find battery wire

I would like to help you, but I am at a small disadvantage here....
You lost WHAT battery connection? WHAT battery wire are you looking for? Do you mean the Keep Alive Memory (KAM) and the ignition (IGN) battery feed at the radio harness connector? Do you think you may have "lost" the battery feed due to blowing a fuse during trying to wire the new radio?

Replaced battery in 2006 accord se, got the code, how do i rest the radio?

turn the radio on. You should see the word "code". type in the code on the numbered station selector buttons. You should hear a long beep when the code is accepted and the radio should work although it will not have the preset stations in memory like it did before it lost power.

No power to radio memory

Battery power to radio lost when ignition off.

Radio must have one wire with battery voltage at all times to preserve memory feature..

Usually the YELLOW one, but not always.

Check all fuses. . Some have 2 or 3amp fuse in rear of radio.

If I replace my own battery in a 2006 Honda Accord. Is there any programming that gets lost and needs to be redone?

Get a memory saver from walmart for a few dollars or so. It plugs into the cigarette lighter and will prevent memory loss from changing the battery which will otherwise erase the radio codes and render the radio disabled for anti-theft reasons.

If your battery does die, and goes below a certain voltage, then go to the website and look under the 'owner's' section and follow the procedure for entering the radio code after you have supplied the website with the information from the owner of the vehicle.

Good luck on changing your battery without losing electronic device memory.

Battery replacement

who ever replqaced your battery failed to do it properly. You have to supply a voltage (usually thru alligator clips to the battery cables) so the memory is not lost in the keyless entry system , dashboard, & radio which all now need to be reprogrammed by a Hyundai dealer
