The cold boot time is less than 30secs on mine after the ACC+ and constant power was cut and reattached(not sure if there is a small battery inside to keep it running for short amount of time). By just cutting the 12v Acc line and reconnect it, the unit takes less than 5 seconds to see the radio...

I find it a great upgrade considering I never knew how to use Bluetooth for phone calls or music playing, or rear view camera, or dashcams. Soon I can run them all plus a lot more (Nav app, games, movies, OBD2 with torque) all on one unit. It is a better and safer solution than trying to use...

I am not familiar with 2009 Mazda 2 so the following is only what I know: It is possible to use interfaces like axxess aswc-1 or canbus to send the steering wheel signals to the head unit as long as the unit has the pins for receiving the predefined signals. The interface converts the button...

Also google "transmission flush machine". Professional transmission shops have this to flush, in addition to the drain and transmission pan replacement. Though the transmission fluid flush is rarely recommended if your fluid is already dark or smelled burned (for cars with more than 70k miles)...

Do you remember how much trans fluid (I assume this is auto trans?) was needed for the flush and refill?

Update: steering wheel control works beautifully now. Here is the mistake I made and how it was corrected: Mazda 24pin pinout diagram ( I can't find the mazda 5 one for 2nd gen. so had to assume all Mazda 24pin harness share the same pinouts) There are wires from the console 1N and 1P for...

My head unit did not come with canbus or a harness for it. I wouldn't know if the hardware is built in to support it. I will try connecting key2 with sw2 and see if it works. I never used Sirius so I am the wrong person to answer about the antenna connections. One thing I would try, if I ever...

Still no idea but I did the install today and took this photo showing that connector: This USB adapter looks to be the same: https://www.aliexpress.com/item/1589056125.html I am going to order the following and replace the stock one. https://www.aliexpress.com/item/32359513282.html Here is...

At how many miles was the changed and has it been changed before? It sounds like the friction plate did not get enough friction, common reason not to do the flush on a already worn-out transmission.

Today I received the head unit (android 7918) in the mail and start connecting the wires. Here is what I have so far: The orange harness on the left will be connected to the console wiring. The black harness on the right will connect to the head unit. One question: Should the blue wire from...

Thanks. I will run some bench test with the stock unit and the aux/usb pin to confirm and see if I can just grab one of those adapters or start thinking of adding the aux adapter and a USB hub (lol) so the android stereo will be able to support more USB ports (plan to have two dashcams and a...

It is apparent that Metra 70-7903 harness did not come with the steering wheel control pins (Key1) but the android radio does. Amazon reviews are helpful: https://www.amazon.com/dp/B0002BEVXY/?tag=m20b7-20

The dark colored top socket in the first photo is for the powered antenna. The pin inside that small rectangle is for receiving the antenna pin, and the pin next to the square is for the blue wire (12v). Metra has an adapter for it (40-HD10). It's not proprietary adapter. Metra's adapter comes...
