This amplifier is different than E65 Logic7 amplifier, it runs different software and cannot be installed on either. This amplifier has 9 channels vs E65 with only 5 channels. This amplifier controls all the speakers on the car, so if it goes bad you will not hear any sound in any speaker. But not always amplifier is the problem, in some cases other modules go bad, interrupting MOST network and you will not hear any sound even with working amplifier. So here i will explain how to diagnose if it is the amplifier or something else went wrong. This amplifier has a diagnostic LED, which will show lots of things you most likely don't know about. Here you can see where it is located.

BMW Factory Audio Explained. BMW factory audio systems explained It’s critical to know which BMW audio system you’re starting with! BMW has three different levels of original-equipment sound system.

So look at that LED, turn on the radio and look at it: basically: blinking yellow -check or bypass sat tuner or Bluetooth tel module no yellow- amp is bad steady yellow but no sound or bad sound- amp is bad. Steady yellow means its getting input fiber optic signal from the head unit (CCC or CIC) and output signal travels to the head unit correctly through other units, so you should hear the sound in most cases, but rarely it also could be some software glitch with CCC, when you don't get sound with working amp.

Try CCC reset. Blinking yellow means AMPLIFIER IS WORKING and getting input signal from the head unit, but output signal is somewhere lost due to the next bad unit in the loop. So you just need to find a bad unit and either bypass it or replace it with a working one. Most common units to fail are: Sirius satellite unit, Bluetooth telephone unit. No Yellow LED, but you can see blinknig red LED deep inside most likely means 3 things:.

amp is bad. no power getting to the amp check last 2 thick wires red and brown 12V should be present always, otherwise check fuses in the trunk. No fiber optic input getting into the amp from head unit, but in this case you should see a red LED on for 15-20secs, this means amp is waiting for a signal and if no signal present it will go to sleep mode. Easy to check, you should see a blinking red LED in the CAR CONNECTOR with the amp fiber optic connector disconnected. If its blinking it means head unit is sending signal to the amp and amp CPU has to accept it and send the output signal back to other units and head unit eventually.

Rarely, But if no red led present in the connector it means no signal is coming from the head unit due to either bad head unit or some fiber optic wire damage. If you remove head unit and you see a red light blinking, you should see the same blinking at the amp connector. So basically you should get steady yellow LED at the amp, which will indicate the network is working, bypass not working modules and if amp is good you will get sound back to your car! These amps are much better design compared to E65 design, but they still go bad due to following reasons:. Water damage especially on convertibles 6 series, almost always we see this problem: It happens when water drainage pipes get clogged up with dirt and thanks to smart design all water leaks onto the amp and other units.

Please always clean those pipes with compressed air and some soap. On 3 series we see rear taillight bolts getting loose and therefore it leaks water inside. Actual CPU failure or other things go bad inside the amp.

We can help in this case, but can not guarantee 100% success, usually we see 60-70% success rate vs 90% e65. Good thing these amps are quite cheap on Ebay or junk yards, or new from the dealer 1200$.

For awhile the system was working well. After that the speaker on the left side started popping and cutting out the rest of the speakers. I took it back to the local stereo guy and they told me the speaker was bad and the only way to fix it was to remove it or replace it.Unfortunatly now Im noticing that my navigation wont boot and when the system cuts out the volume is lowered drastically. Any idea what the issue is. ↓.

Intro When the 2007 BMW 335i coupe arrives in showrooms on September 1, it will be the first gasoline-powered Bimmer in a generation to incorporate a turbocharger. With a sleek, newly designed body, the 300-horsepower 335i is the most powerful non-M3-series BMW coupe ever, and is also the most high-tech. Driving the sport-tuned 335i is a pleasure: bucket loads of torque in each gear are made usable by precise steering and magnetic handling. Our tester was equipped with the optional Sport package, which gave us sport seats with power-adjustable backrest width, 18-inch alloy wheels with W-rated run-flat tires, and an increased limited top speed of 155mph. Also available is the Cold Weather package, which adds a headlight cleaning system, heated front seats with expanded heating area, and a ski bag. (We venture to suggest, however, that those wishing to muck around in the new 3-series coupe in the snow wait for the launch of the all-wheel-drive new 328xi later this year.). In the cabin, the 335i delivers all of BMW's latest optional tech systems: Bluetooth hands-free calling, GPS navigation via the second-generation iDrive interface, and adaptive cruise control are all offered as stand-alone options.

A surround-sound Logic7 audio system with the ability to play advanced digital audio formats (MP3, WMA) comes standard, as does a generic auxiliary input jack for those wishing to stream their iPod libraries through the car's 13 speakers. Other standard tech includes adaptive headlights, adaptive brake lights, and a unique seatbelt presenter, which (in theory) saves you the trouble of stretching. Those looking to buy the 2007 335i coupe will have to stretch to $41,295 for the basic model, and a bit further according to their a la carte option preferences.

The cockpit of the 2007 BMW 335i is a snug fit. Headroom is adequate for those taller than 6 feet, but NBA stars will have to open the sunroof to drive it.

Leatherette sport seats grip the driver's and passenger's hindquarters in a way that suggests the car's designers anticipate plenty of lateral acceleration. And while coupe rear seats are often only for insurance-reduction purposes, those in the 335i are surprisingly usable for shorter grown-ups. A central rear dividing console means that the 335i is only a two-plus-two, but the fact that it is a two-plus-anything is commendable. Leather seats-including a superluxurious Dakota leather package-are optional and available in a choice of three colors. Dark burl walnut wood trim for the dash, door panels, and front and rear central consoles comes standard on the 335i, with the option of light poplar wood or brushed aluminum at no extra cost. A thin strip of wood (or aluminum) traverses the entire width of the dash, giving the cabin a wide perspective. One of the most unique interior tech features of the 335i is its automatic seat-belt presenter-a mechanical arm that deploys to serve up the seat belt to driver and front passenger each time they enter the car.

After offering the belt for about 10 seconds, the arm retracts, irrespective of whether the belt has been taken or not. We found the autopresenter a novelty, then a pain, then a useful feature: it takes some time to quell the reflex urge to reach around and grab the belt manually-a course of action that is sure to result in the belt becoming detached from the arm, and so completely out of reach. With some practice at -ahem-restraining ourselves and waiting for the autopresentation, we found the device useful as well as deliciously kitsch.

The 335i's auto seat-belt presenter deploys to serve driver and front passenger with their restraints. The 335i's head unit comprises a wedge-shaped panel into which is set the HVAC controls, buttons for the optional heated seats and park-distance control, and the standard single-disc CD player, which plays MP3 and WMA CDs while providing full ID3-tag information on the dot-matrix LCD display for both. We found the audio system intuitive for navigating homemade CDs: using the head unit's hard buttons, we were able to make folder and track selections, although the two-line display limited the number of tracks shown at any one time. All 2007 BMW coupes come with a central console-mounted generic auxiliary input jack as standard, and plugging in our iPod Nano enabled us to stream songs through the BMW's audio system, although without the option to control anything other than volume via the head unit. Those looking for a more advanced iPod integration can purchase a BMW interface for iPod as a dealer installed option, which devolves total control of the iPod to the stereo buttons while displaying track and artist information and simultaneously charging the player.
