If you have the touch screen and no rse I’d say this is a no brainer.
Using navcoder with usb to serial upgrade#
The whole upgrade had cost around as much as one nav tool box but you get a whole load more and a massive screen. Overall very impressEd there’s a decent dsp on the head unit so excusing the bow sound hiss with music playing the sound system sounds so much better than before (no complaints before either!) I will keep this updated and add pics over time. I can’t set the time but the resler interface looks like it may be the way along with ibus app. I can’t get the stock reverse cam to work but I’m not giving up yet The dab window area is pants so may get a shark for this. I am waking on a replacement most adapter on this. However make sure it all works first as this will definitely kill your warranty!!!)Įventually got it all in and all is well except I have a bit of a hiss when no music plays like the amp The back of the head unit to make it fit (there’s a big nearly empty metal box on the back. Unfortunately unlike the early dash on the l322 it’s very tight I had to trim I plugged one end of the most cable in and the loosely ran it over the seats and unplugged the old one from the amp and replaced with this. Plugged the dab/CarPlay usbs in, plugged the front rcas from the head unit into the most box and splice then into the loom. I ran an ibus feed (we still have it!!) from the clock (spliced) to the ibus input on the headunit and an ignition live from the cigar lighter.

Using navcoder with usb to serial iso#
I then bought a jaguar m to iso f connector and then a bmw f to iso m connector and plugged them together. This is fairly low priority but will happen at some point. Specifically noting the head unit does have rear screen outputs once I find some screens the right size. I thought time for an upgrade as I won’t be losing anything with the rears here. Instructions on setting up the debug environment are available in the Operation and Testing section.Headunit Upgrade on 2006-2010 - Work in progressĪ while back i mentioned that my rear headrest screen one was always broken since I had the car then the second one died and within about a month the laser died in the dvd changer.

Using navcoder with usb to serial serial#
Use your favorite serial monitoring software – I personally prefer PuTTy. For the UNO R3 we use pins 7 (Rx) and 8 (Tx) for our Software Serial. This allows us to use a USB-TTL converter to monitor what the Arduino is seeing and doing. The Arduino programming includes optional debugging via Software Serial.

Pins 14 (RESET) and 15 (SENSE) are not used for this project. We do not need this feature, so we ground pin 8 (SI), the comparator input. Pins 7 (SO) and 8 (SI) on the TH3122 can be used as a universal comparator. Pin 3 (VTR) is connected to VCC It sets reset timing (See TH3122 Datasheet). This is used in the Arduino programming to tell when it’s safe to send data onto the K-Bus. The SEN/STA signal stays High while there is data/activity on the K-Bus, and goes Low when there is noĪctivity. Pin 9 (SEN/STA) is connected to the Arduino’s digital input pin 3. Pin 10 (RX) is connected to the Arduino’s receive pin. Pin 11 (TX) is connected to the Arduino’s transmit pin. The TH3122 will automatically re-enable VCC (Pin 16) once it sees activity on the I/K-Bus – which will wake up our arduino. We will use this in the arduino programming to shut down the arduino when there is no activity on the I/K-Bus after a certain time period. Pin 2 (EN) enables the +5 Voltage regulator output on pin 16 (VCC). I stuck with 1uF for flexibility (smaller variety of parts), due to the MAX232 datasheet specifying 1uF – for the RS232 interface. VCC (Pin 16) provides the arduino with +5V It is also connected to a 1uF capacitor (C5) to reduce short time voltage drops.Ĭapacitor C5 is suggested to be above 2uF in the TH3122 datasheet. The circuit has a 47uF capacitor on the +12V line to reduce short time voltage drops. +12V supply voltage passes through a diode (D1), and connects to pin 1 (VS) which powers the TH3122. The RC filter is a 10 ohm resistor and a 100pF non-polarized capacitor. The RC filter minimizes EMI on the BUS line, and is recommended per TH3122 datasheet. The BMW K-Bus wire passes through an RC filter and then connects to pin 6 (BUS) on TH3122.
