Everything I wanted for my boat

My 4 yr old Kenwood died. I was looking for a unit with BT and 3 pre amp outputs for the old configuration, the amps,SW etc. Once I figured the unit out by disabling the SW since I have one the receiver sounds great. The App remote with the equalizer is fantastic. The BT range has a 100' range, that's amazing. Make sure you buy the right remote RM-X11, which Sonic for some reason doesn't carry. I also installed a remote USB, you will need that to utilize the remote app you download on your phone. I Highly recommend this receiver.

Great Deck for the Boat

I waited a bit to post a review as I wanted to get out on the water with it. After 3 times out, I figured out all the functions as the manual is a good start but doesn't expain everything. USB thumbdrive works good as well as ipod interface. The deck can take over all the features or you can hit a few buttons so you can control everything from the Ipod itself. (it can get cumbersome trying to go back, scroll, and select from the deck itself while a song is playing).

I love the 3 pre-outs as I had 3 channels with front rear and bass. Setting up bluetooth was fairly simple and pandora worked great.

Excellent unit

Bought this to instal in the fairing of my Harley. The display is easily viewed in direct sunlight. The controls are user friendly and the front USB is perfect. The rear outputs are great for the amp hook up. Makes fantastic sound at 80 mph. Installed 3 others in motorcycles. Best marine unit ever. SONIC SERVICE IS EXCELLENT!!!!

Great overall headunit

I've gone though many units before. There are 3 things I always look for.
1. Built in Bluetooth
2. Rear USB (Front optional)
3. Aux Port

This unit delivered. It has front AND rear USB free, not like most that have both but have a Bluetooth adapter attached to either one.

If you have a usb with a lot of songs that are organized in folders then it is tricky to navigate your folders with this unit but once you get used to the album system its fairly easy.

Sound quality is great, although a bit quite as this was installed in a 19' bow rider paired with Kenwood KFC-1653 Speakers.

The remote is the same remote Sony has been using for a while now, a new feature APP Remote V2 is also available. People with smart phones download the app (IOS/Android) and can change song, source, options. Straight from the phone via Bluetooth, although if you are steaming via Bluetooth audio then the app remote will not work.

Overall I would recommend this unit to anyone who wants the most bang for their buck, lots of features and robust keys make this a must for people looking for a high quality marine headunit.

great radio for the cost

Good radio for the boat, wish they had a way to keep station memory with out draining battery. Love the Pandora with the iPhone, charges while being used. Was concerned about data use but it seems reasonable, we use it for hours at a time.

Soney MEX-M70BT

Great radio, I installed this in my Harley and the performance is just what I was looking for in a weather resistance package. The controls are easy to read and work even in gloves.

Awesome marine stero

This stereo is what I expected plus more. Went through 4 cheap stereos last summer that were not marine. I hope this one stands up. This stereo cost the same as the 4 cheap one I ruined by getting rained on.
