My 2 month old kenwood 9990 crapped out on me .The startrup screen just keeps rebooting over and over.The shop I bought it from sent it back to kenwood for warranty. Now the shop says the reason this happens is because this unit draws too much power or something like that. They told me to wire a relay between the battery and the headunit and I should be good to go. Has anyone heard of this or is it just a load of crap.I'm pretty pissed off that my new $1000+ headunit already had to go in for service and I had a hole in my dash for over a week. I have read on the kenwood forums that other people have had the same problem but never heard of using a relay to fix it
