Some of our customers had asked how they could completely reset their AL Priority system to the original factory parking-only firmware, in order to load or restore a saved copy of an older firmware or simply to perform a hard reset.
1. Make sure your ALP system is on.
2. Press and Hold MENU button (yellow first, then blue, then start flashing in different colours). When flashing starts, release the MENU button, then quickly press MENU button 3 times.
3. ALP system will take a few seconds to restore to its original parking-only firmware. Any VoicePack for HiFi Control Set will also be erased.
4. Load a saved copy of your ALP firmware or download the latest from ALPupdate.com. Reload VoicePack for HiFi models.
