Hi,

The radio/ cd unit, for your model Jeep, has a built in security code. When disconnecting the the battery it activates the security. The reason for this is to discourage someone stealing the radio, as it renders the unit useless. To re-activate the unit you will have to enter a pin number, which should be supplied with the vehicle when bought from the dealership ( check in your operating manual). If you don't have the pin number, contact your Jeep dealer, who can supply the required pin code. Usually the dealer will re-activate your radio/cd unit free of charge.

Best of luck

Typically to get the code you have to have the serial number of the unit and call a Honda dealership to get the code. Sometimes in years gone by, there was a credit card sized card that had a sticker with the serial number and code. Sometimes the sticker is even stuck on the owners manual or the inside of the glovebox.

It sound like you are going aftermarket so I would think that the code is not needed as the code was only for the factory radio itself, not the rest of the system (speakers, etc..) Call the radio installer and ask but I don't think you need the code.

Honda outlines it here:
https://radio-navicode.honda.com/

You can retrieve your 5-digit code if you have your VIN (look for the plate at bottom of windshield on drivers side, looking from the outside), your phone number (the one Honda has on file, gathered when you bought it from the dealer) and the radio serial number.

They give you instructions on getting the radio serial number from the radio display which did work. Turn on ignition, have radio off and while simultaneously holding the 1 and 6 radio buttons push the "on" knob. Two code will flash... a U code and a L code, each followed by 4 numbers. Those 8 numbers (without the U and L form the radio serial number

Any Honda dealer will be able to supply the code for your radio serial number matched with your vin # .
Check in your owners manual.....it may be written in there or it may be on a card in there.
Write it in the manual when you do get it from the dealer.......which is the only place you can get the code.

you need to go to honda dealer they are only ones that have that code sorry to tell u but thats your only hope tell them you need the radio code

look in the owner manual and it will let u know how many hour u are suppose to wait. to have another 10 chances

check in drivers door jam , glove box there should be a little sticker somewhere there with a 5 didgit code that will be youre code or in with youre owners stuff,once you try putting the wrong code in three times it will show error then you will need to disfconnect the - battery cable to try again, if you fcant find the code you will need to take to dealer and ask them for it they should have it if not you will need the serial number off the radio and they can get it with that

THE CODE IS
