Head unit restarting while driving??
- Stock C5 with Bose system
- Following installed 3 weeks ago:
- JVC kw m740bt head unit
- This PAC wire harness
- This antenna Adapter
- Power and ground are soldered, but I was new to soldering so it's a clump of solder all in one location on the wire.
- Other wires use crimp style connecters.
- All wires WELL shrink wrapped, except one has a tiny bit of exposed copper.
This happened today.
- Drive and listen to music without issues
- Head Unit restarts arbitrarily
- It doesn't lose power. No period of blank screen! It goes from on and running to -BOOM- JVC Welcome Screen.
- Restart is NOT effected by bump in the road. Happens during smooth ride, doesn't happen during pothole.
- 10 or 20 seconds later it will restart again
- After several restarts it said "Please park your car in a safe location and turn the ignition OFF and ON again." Doing so restarts the head unit.
Cause?
Well, this is where I'm hoping you guys can help!? I'm a COMPLETE novice, but willing to get my hands dirty trying anything.
Here are my ideas....
- It's overheating normally. No solution. (Outside was ~70° every day since installation, today hit 100°)
- My Bose speakers provide less Ω ohm resistance than the head units requires, causing it to overheat.
- No idea how to test or fix.
- My crappy soldering skills are causing poor draw through power and ground? Redo properly maybe?
- Check the fuse box for corrosion
- Head unit draws more power than stock wiring and deliver? Run custom thicker cables up to battery myself?
- Check the battery terminals for corrosion (DONE - it's clean as brand new)
