Question: This item did not fit my 1997 Mazda 626 as advertised. The cables don't correspond. Is there something I should know to make it work?
Document: This is not a great stereo, but it is great for the money. I wanted something cheap for my old Wrangler (since you can't lock a soft top). This fit the bill. Installed easy and works well. It does not handle USB and SD memory cards as advertised. If you want to put a buch of songs on it, this it will play them either in order or randomly. It does not work if you put the songs into subdirectories.
I never used the device for the radio, or usb slot.But I did had once it corrupt my sd-card somehow, don't know if it did it, or my laptop did it. One of them did, and I had to format and start over.Playback of the music sounds good to me, as good as my higher quality sony unit I use to have.The only thing that didn't work for some reason was the line-out rca cables that goes to an amp.
The sound from the AUX port is very low and the AUX port only plays off one side unless you play with the cable and press it to one side. I've tried different cables and know the cables work and it's the port.
First day i receive the item, plug everything in and ensured power and ground with test light. Radio still dead. Made multiple attempt's making sure i did not make a mistake, there's power and there's ground! No Work...
The controls are very awkward and very poorly documented. The unit seems to be very finicky about the formatting of SD cards -- still trying to find a solution that allows me access to all of the songs. There is often a static-like hum when the device plugged into the AUX port is also plugged into a charger. I don't know if this is the fault of the receiver, my cables, or just an unavoidable consequence.
Can be difficult to install a newer vehicles not necessarily anything to do with the radio itself, but I did run into problems. The quality of the item matches the price. No real complaints, but I wish I would've paid a little more and got something nicer.
I finally decided to make the jump and get rid of my stock stereo and get one that could play my iPhone so I got this one. It seemed to fit my needs and was affordable. Well, when I got it installed I thought the installer must of made a mistake as the sound didn't seem right? After a few days of testing it out  and talking to other installers they said it was a stereo problem.
Spent an hour hooking this thing up. I was excited to see it turn on and hear the buzz of channel 87.5. But when I turned it to my favorite station and turned it up loud enough to hear it, the audio started to cut in and out repeatedly. To all those people who just assumed anyone who gave 1 star didn't know what they were doing hooking it up (like I thought), you are wrong. This item should not be sold in this country.
I bought this for my VW Beetle and had my brother install it. That took about an hour and didn't seem too bad. I bought a new antenna but this radio doesn't seem to come in clear. I am not sure if it's the radio or antenna or combination of both? I wanted a simple radio and something I could play my ipod thru and this seemed like it would "fit the bill." My big complaint about this radio is the buttons are SO SMALL you cannot see them!
Now down to the deal breaker for me. The radio does not have a CD player.. Yes i knew this, but I figured it would make up for that by having a kicker tuner so all the radio stations would be awesomely clear. NOPE. I know I have an older car (95 ford ranger), but give me a break. I live in nashville, and could barely pick up anything other than the 4 main stations.... So that is why my review is so low.
