Experiencing a “Memory Full” error on your Pioneer touch screen car radio when trying to pair a new phone? You’re not alone. Many users encounter this frustrating issue, especially after pairing multiple devices over time. This article will guide you through the steps to reset your Pioneer touch screen radio and clear the Bluetooth memory, getting you back to seamless connectivity.
Understanding the Bluetooth Memory Issue on Pioneer Radios
Pioneer touch screen radios, like the popular AVH-X2700BS and others in the AVH series, have a limited memory capacity for storing paired Bluetooth devices. Once this memory is full, you won’t be able to pair new phones without first deleting older ones. The problem arises when you can’t access the Bluetooth menu to manage these devices, often indicated by a greyed-out menu option on the screen.
The Parking Brake Wire and Accessing Settings
A common reason for being locked out of the Bluetooth settings menu is the parking brake safety feature. Pioneer radios, and many aftermarket car stereos, are designed to restrict access to certain settings while the vehicle is in motion. This is a safety precaution to prevent driver distraction. To bypass this, the radio requires a connection to the vehicle’s parking brake wire. When the parking brake is engaged, the radio senses this and unlocks access to menus like Bluetooth settings, video playback, and other potentially distracting features.
In many DIY car audio installations, the parking brake wire is intentionally left disconnected, especially if features like DVD playback are not frequently used. However, this omission can prevent you from accessing crucial settings later on, including resetting the Bluetooth memory.
Why Simple Resets Often Fail to Clear Bluetooth Memory
You might have already tried common troubleshooting steps like disconnecting the car battery or pressing the reset button on the radio’s faceplate. While these actions can reset some radio functions and clear temporary settings, they typically do not erase the stored Bluetooth device list. The Bluetooth pairing information is usually stored in a separate, more persistent memory section that requires specific menu access to clear.
Steps to Reset Your Pioneer Touch Screen Radio’s Bluetooth Memory
To effectively reset your Pioneer touch screen radio and clear the Bluetooth memory, you will likely need to address the parking brake wire connection. Here’s a step-by-step approach:
-
Locate the Parking Brake Wire: Refer to your Pioneer radio’s installation manual and your vehicle’s wiring diagram. Identify the parking brake wire from the radio’s wiring harness. It’s usually a dedicated wire labeled “Parking Brake” or similar.
-
Connect the Parking Brake Wire (If Disconnected):
- Safely access your radio’s wiring: This may involve partially removing the radio from your car’s dashboard to access the wiring harness. Consult your vehicle’s repair manual or online resources for instructions on safely removing your car radio.
- Locate the vehicle’s parking brake wire: This wire is typically found in the vehicle’s wiring harness near the steering column or fuse box. It’s the wire that receives a 12V signal when the parking brake is engaged. You may need a multimeter to verify the correct wire.
- Connect the radio’s parking brake wire to the vehicle’s parking brake wire: Use a proper wiring connector or solder and insulate the connection for a secure and reliable link.
-
Engage the Parking Brake: Turn your car’s ignition to the “Accessory” or “On” position (without starting the engine) and fully engage the parking brake.
-
Access the Bluetooth Menu: Navigate through your Pioneer touch screen radio’s menu system. With the parking brake engaged and the wire connected, the Bluetooth menu option should now be accessible (no longer greyed out).
-
Clear Bluetooth Memory: Within the Bluetooth menu, look for options like “Device List,” “Paired Devices,” or “Memory Clear.” Select the option to delete paired devices or clear the Bluetooth memory. Follow the on-screen prompts to confirm the deletion.
-
Pair Your New Phone: Once the memory is cleared, you should be able to pair your new cell phone without the “Memory Full” error message. Follow your radio’s instructions for Bluetooth pairing.

Firmware Update as a Potential (But Unlikely) Solution
While a firmware update can sometimes resolve various software glitches and improve radio performance, it is unlikely to be the primary solution for clearing Bluetooth memory. Firmware updates typically focus on system-level improvements and bug fixes, not necessarily user data like stored Bluetooth devices.
However, if you are running very outdated firmware, updating to the latest version might be worth considering after you have addressed the parking brake wire issue. Check Pioneer’s website for firmware updates specific to your radio model and instructions on how to install them.
Seeking Professional Help
If you are uncomfortable working with car wiring or are unable to locate the necessary wires, it’s always best to seek professional help from a qualified car audio installer. They can quickly and safely connect the parking brake wire, allowing you to access the Bluetooth settings and reset your radio.
Conclusion
Resetting your Pioneer touch screen radio’s Bluetooth memory usually involves understanding the parking brake safety feature and ensuring the parking brake wire is properly connected. By following these steps, you can regain access to your Bluetooth settings, clear the memory, and enjoy seamless Bluetooth connectivity with your new devices. Remember to always consult your radio’s manual and seek professional assistance when needed to ensure a safe and successful resolution.
