I purchased this product as an add -on to the MB Quart GMR-1. Connections are easy. Installation was a breeze. Connects my Ipod to the head unit and also has a usb connection for flash-drive.

Great value

April 28, 2016

The product is well made and sealed from the elements. At the time I selected the weatherproof USB/Audio connector, I did not realize how long the attached cables were. Although I can still use the product, for someone considering purchasing the product, make sure the cable length is not an issue- they are 10 feet long. I failed to see this in the description, thinking it was a double sided adapter. Mia culpa! It is still a great buy.

I'm replacing the aux on my boat.

provides a clean look when mounted on the dash.
Not the most durable product though. Be careful, you can push the headphone jack through the back of it pretty easily.

I need aux input for my stereo headset, will this fit and replace a vehicle 12 Volt charging outlet?
A shopper on Jan 28, 2017
Best Answer: It's a simple extension , so it depends on your head unit. and where you connect the other end.

I have a 2009 Mercedes Benz C300 with the aux cord in the glove box. Does this MB Quart PSAP-2 allow any phone to connect to the stereo system through the aux cord?
A shopper on Jul 11, 2016
Best Answer: That is a complex question. First the Mercedes sound system would need a USB connection on it. That would mean research or pulling it out. Then, if it does have a USB port, you would need to be concerned that your particular phone make and model will work well with the way the MB Quart PSAP-2 is wired and how the Mercedes Benz engineers have wired the USB port. If all 3 of these folks have followed USB wiring standards, it should work. PS: the MB in this device name (MB Quart PSAP-2) does not stand for Mercedes Benz.

Can I hook this up to a Kenwood KAC M1824BT and play music through the USB and the Aux?
Rojelio O on Aug 26, 2016
Best Answer: Yes that kenwood amp will connect perfectly to the amp.

Read the MB Quart USB connectivity instructions THOROUGHLY to make sure it will meet your needs.

The mb quart already has Bluetooth.
Go with a Bigger Amp unless you already have the M1824BT or have space limitations

Will this charge a cell phone or MP3 player while in use?
A shopper on Apr 2, 2016
Best Answer: Yes. I just hooked up my phone to this and got a charge signal on the screen. In particular the radio is a Clarion M303 to an iPhone 5 via the PSAP-2.
