I have a Pyle PLDNV695 radio that when you shut it off for more than 10 seconds, you have to reset the radio and reprogram the radio stations. What could the problem be ???

There are 1 or 2 large fuses in the main fuse block near the battery. 100 amp and 150 amp usually. Pop off the clear plastic tops and check those. Most times those will require separating the block to unscrew the bolts that hold them in.

You need an interface module so it will work with the vehicle ! The radio is hooked up to the class 2 serial data bus , if you don't hook it up right the vehicle will not start an run !

call a dealership don't try rigging anything you may have to have a official dealership reset it for you but first try disconnecting the battery for 10 minutes put key into ignition and turn it to start position as if you were starting the vehicle to help drain capacitors then find something to occupy you for atleast 10 mins while battery is disconnected (you may have to reprogram your radio stations so make sure you know them.

I think you tune the station you want and hold the button in for about 10 seconds or until the radio acknowledges the change.

1. Connect the FM antenna and the AM loopantenna at the back of the unit. Rotate the AM loop for better reception.
2. Press AM/FM.
3. Tune a station by pressing TUNER+/-repeatedly until the desired station is found.Alternatively, you can press and hold thesame buttons down for about one second toactivate the automatic search function. Inthis mode the unit will automatically tunefrequencies until it finds a station.
4. Repeat step 3 to tune to another radio station.
5. Press AM/FMto select between FM and AM.Storing Radio Stations

The unit can store up to 40 radio stations (30 preset stations for FM and 10 preset stations for AM) in its memory. You can enter every single radio station yourself or the unit can store all available radio stations automatically in ascending order

Automatic Preset Programming
1. Press AM/FM to enter the AM/FM mode.
2. Press and hold AM/FM for two seconds to start automatic preset programming.
3. Radio frequencies will be browsed and radiostations stored automatically. When all the available radio stations are stored or all 40(30 preset stations for FM and 10 preset stations for AM) memory locations are full,the auto preset programming function will stop.

Manual Preset
1. Tune to a radio station (see "Manual tuning"for details).
2. Press MEMORY. While the Program Preset number is still flashing, input your desired preset number using the numeric buttons or press CH+/-, then press MEMORY to store it.

Retrieving Preset Stations
1. Press AM/FM to enter the Tuner mode.
2. Press CH +/- to search up or down for thepreset stations or directly press the numeric buttons.

When you replaced the battery, it reset the radio. You will need to reprogram the radio stations you want on fm. Find the radio station you want and then press the set button on the radio and then the corresponding number on your radio (ie: set1, set2, set3, set4 or set5)

Hmmm, I haven't heard that one in a while. Easy fix. Pop your hood and disconnect the negative batter terminal for 10 seconds or longer, then reattach. You may need to reprogram in your radio stations.

Turn off the radio and disconnect the battery for 30 seconds. Make sure the radio is off before you disconnect the battery. once the battery is reconnected, turn on the radio and eject the CD and reprogram the stations and clock. Good luck and hope this helps. 

the radio station buttons numbered 1 2 3 4 5 6. enter the 5 digit radio code there. if it locks up or goes to error you must remove the negative (-) battery cable to reset the radio and try again. it will let you try 3 times.
