iSimple ISGM655 Premium Factory Radio Interface for iPod, iPhone or iPad, Android and Other Smartphones

I researched this product for awhile before making this purchase. I installed mine on an 03 Chevy Silverado. I've had it installed for a week now with no issues at all. I'm running the bluetooth with an Iphone 6 and it has performed flawlessly. After initially connecting to the bluetooth, my phone automatically connects to the device when I start my vehicle up, the only thing I have to do is hit play on my phone. The usb option is a nice option to have for long drives when the bluetooth runs down the battery life on my phone. The bluetooth phone option work great. The microphone picks up your voice very well, but since my truck has an exhaust on it I decided to run the microphone close to me so that it wouldn't pick up as much of the exhaust noise. The manufacturer does not send you clear directions on how to use the factory radio buttons for your device, but you can go to the web and get the directions there. On the Iphone you can also save them to your ibooks app for quicker access.Installation was simple, but time consuming. I'm a neat freak so I have all my wires ran symmetrical to the factory wiring. On the Silverado, there's not a lot of room for the actual box to sit behind the radio. So I had an open compartment behind where the passenger side air bag switch is, so I mounted it there. The wires for device are all long enough to run everything pretty much wherever you want to in the front cabin. When installing the radio back into the vehicle is the only problem I ran into. The wiring it split two ways. and where its split at is so close to plugs that go into the back of the radio that its hard to get the support plug back into the mount hole that's on the back of the radio. It will fit, but its a tight fit. I took some time installing the usb port. I wanted it to look factory in my vehicle so I removed the 12V port on side of the center console and placed it there. The hole for port is larger than the usb adapter, so what I did was take the actual 12V port out of the black round housing that it was in, and then cut the end of the 12V port out so all that was left the metal piece that goes inside the black round housing. Then wrapped the usb adapter with electrical tape enough that when I slid it inside the metal piece that I had to really push to get it into it. That way when you go to use the usb adapter, when you go to pull the cord out, you won't pull the whole adapter out with it. Then I drilled a hole underneath the usb adapter for the reset switch. I installed the microphone next to the driver seat. I ran the wire in between the gap of the center console, and the adapter that holds the switch slides right over the console with a nice fit. All the wiring for the usb adapter and the microphone i zip tied underneath the center console. When you removed the center cupholder piece from the center console, there's a lot of room underneath it. So I zip tied my wires tightly together and ran them down the right side of the center console until the remaining of it was underneath that cup holder piece, then I zip tied the remaining all nice and tight and left them there. I'm happy with the way it turned out, and no-one can tell that its not factory by looking at it. I uploaded the pictures of my install just to show you what the finished product looks like.Another option for the usb install if you wanted to use the manufacturer's provided mount plate, would have been to put it inside the center console piece, either on the inside, or at the bottom.Also, one thing I did read up on for the Iphone, if you go into your phone and rename your Iphone without the apostrophe in it, for example Jon's Iphone, if you rename it Jons Iphone, somehow it improves functionality.

I have had this unit in my 2006 Tahoe for almost 4 years. The stock head unit had an XM receiver that failed so I liked the alternative that this unit provided. Installation was a little tough - shoehorning all of the stuff under the dash wasn't easy... But it worked pretty well right out of the box. About a year ago, the stereo started to reboot and forget everything but the radio stations. It would forget about how many audio CD's were installed. When I went to reset the ismiple connect with the reset button, a number of items in the car would flat and chirp. Then the vehicle stability system would shut down and signal a failure message. All this went away after cycling vehicle power so it wasn't a tool loss.All in all I would say I have got $150 worth of value even though it is being less cooperative these days.

WHEN it works, it is AWESOME! Unfortunately, it has to be reset quite often, causing me to have to re-pair my phone to the bluetooth. Another HUGE issue is that it does not want to work with my wife's iPhone 8 Plus. The audio continuously stops then continues, just as if someone were repeatedly pressing the pause button on and off. This is bad since it is in the vehicle that she drives the most! I will probably get a bluetooth adapter to plug into the aux input of this device just for her to be able to use it, even thought it will not be able to control the phone. I will be trying a few other things to reduce the need to be reset so frequently, but I think it is just not starting up properly with the GM Class 2 bus.As some others have stated in their reviews, I tried replacing it with another unit, however that did not improve anything for me, I'm glad it has helped some others.Although I marked my review as one star that means "I hate it" I plan to keep it, since I do like it when it works, I just wish I didn't have to go through a reset and phone re-pair every time.Just a little background on myself, I'm a professional automotive technician at a GM dealership with 18+ years of experience, and I also have a decent amount of experience installing car audio and aftermaket devices in cars at a professional level.
