Head unit for the Snartnav went out a few months ago, I replaced it and that’s when the issues started. From the day I installed it for 5 minutes after the radio powered up the ac compressor clutch cruise control windows and interior lights wouldn’t work. After 5 minutes everything comes back working. Now the Smartnav powers on like it’s supposed too but as soon as any music plays it turns itself off and restarts. All while the things I mentioned above not working. If I catch it before the music plays and turn it off after 5 minutes everything come back working. Sometimes the smartnave turns on works first time and sometimes it takes 6 hours of messing with it while going down the road. Has this happened to anyone, or maybe point me in the direction to look.
