Post projects and modifications here.
Always on RSNAV
- Goal of this project is to have the device stay powered on after car is turned off.
- We need to know what wire to tap into on the RSNAV, and what voltage and amperage battery would be required.
RSNAV Coin battery
- Project: Add coin battery to keep time.
WARNING: PROCEED AT YOUR RISK. YOUR FAILURE HERE IS NOT COVERED BY THE PRODUCT WARRANTY.
- Required: CR2032 Battery, CR2032 Battery holder, Soldering iron, Solder, Thin electric wires, and basic soldering and assembly skill.
RSA-70XXX Shown below, the procedure for RSA-10XXX is similar. For RSA-12XXX, there will be separate instruction in future.
1. Remove 5 screws as well as the bolts and washers holding the audio jack, and the mobile antenna connector
2. It should look like above before you lift up the backplate. Carefully lift up the backplate a bit. Detach the audio jack and antenna connectors from the backplate.
You may feel resistance while lifting up and that is normal as the thermal pad is sticky. Proceed to lift as you are clear of all the connectors from the back plate
3. With the backplate removed, remove 6 screws red circled, and flip the board from the top.
4. Be careful not to press the daughter board assembly with mic and SD card slot as it can be easily broken if you apply any pressure to it.
5. In the backside of the motherboard, locate PIN 174 shown above. Solder a wire to the pin. Do not short this pin with any other adjacent pins.
The wire attached to the PIN 174 is the positive supply of 3V. Also, solder another wire to any ground point of your choice or the simply tap exactly the same point for the negative pole(ground).
6. Everything should look like exactly like this before you assemble the mainboard back to the display assembly. Proceed to reassemble and take out the wires like above.
7. Solder the wires to the corresponding terminals of the coin battery slot. The failure of reverse polarity may harm the device. Check soldering on terminals, insulate, and mount the coin battery slot using hot glue or your choice of adhesive, fixing mount. Finally, insert a CR2032 battery. This battery may be replaced every few years.
