In 2015 I had first bought a Sony 710 DD. I was sure Sony had gotten FAR better in quality. I swapped out my Bose Nav unit with the Sony. Before I could get my amps and components in, the Sony killed it. Upon reading my iPod Classic 160gb, which took OVER 2 HOURS...it was slow to act on the commands. When it locked up, ALL settings went 100%. Bass, Mid, Treble, Volume...and the only way to get it back was to turn off the vehicle or pull fuse.
So, I brought it back. Got a brand new Pioneer NEX 4k model. Holy noise hell. I have NEVER heard so much whistle, whine, and pop. Each screen press, CD fast forward, Track advance, EVERYTHING had a different noise. But. I dealt with it until I put in my amps and speakers. Thinking the Sony's issue messed up the Bose system. However, installing the amps/speakers made it MUCH worse. So...brought it back, got refund.
On the way home with a huge opening in the middle of my dash I stopped by BB. Picked up a JVC KW-V41BT. Still in my truck today. It's a 2014 Head unit, as the year is on the startup. I have absolutely ZERO noise on this unit. I have NOT had 1 single issue with it. It has 3 way cross over settings that are MORE than adequate for what I need and do. The screen is highly visible at the stock/flat angle, and its pretty well lit. When I purchased it was discounted a bit, so it was hard to pass. Glad I bought it. Even today.
Sony total cost from CarToys was just under $600.
Pioneer total cost from CarToys was same, as they swapped it straight, even though Pioneer was $25 more.
JVC total cost from BestBuy was under $300.
Half the price. No control issues. No noise issues. And it does sound VERY good.
I am changing it out by the end of the year. My nephew wants it very badly for the system in his Colorado, so I will give it to him and get a new model Kenwood Excelon, most models I want are upwards of $500 now.
(hate to see a CD slot in the face if I dont use CDs all the time, but dont want mechless incase I toss an old disc in)
