fixed : budget friendly OBD2 dongle for my car

Question :

My car’s on-board computer system sometimes gives unexplained, rather random, error messages. Up until now, I went to the dealer garage to have my car’s on-board computer system be analyzed and reset. Recently I heard that I could buy an OBD2-dongle myself and read and erase error messages myself. That would be a real time (and money) saver.

Is there any budget-friendly OBD2-dongle that I can use with my iPhone ?

 

Answer :

Yes there are several OBD2-dongles available that can do the job for you. Just make sure that you keep these things in mind when choosing one :

  • make sure the OBD2-dongle is compatible with iOS (as some are only compatible with PCs or Android-devices)
  • make sure the OBD2-dongle’s connection is over Bluetooth LowEnergy a.k.a. BLE (since that’s the only way to be able to connect your iPhone to your regular WiFi-network (internet) and to the OBD2-dongle at the same time)
  • make sure the OBD2-dongle is based on the original ELM327 chip (most cheap Chinese knock-offs are based on problematic, unreliable clone chips)
  • make sure the OBD2-dongle is compatible with the software you are planning to use with it (not every OBD2-app connects equally good to every OBD2-dongle & if you need to erase the error messages, most FREE versions won’t do so you will usually need the Pro version)

One of the cheapest reliable OBD2-dongles I’ve found is the TONWON OBDII Pro Bluetooth BLE4.0 for about €26,- ;

buy it on Amazon.com, Amazon.co.uk or Amazon.de

And do not forget to get an accompanying iOS-app :

most interesting for the budget-wary is Car Scanner ELM OBD2 Pro for about €5,50

(or the more expensive OBD Fusion at about €11,- or even the €20,- OBD AutoDoctor that even has an additional Mac-version)

…so buying into this DIY-solution is cheaper than having your car’s on-board computer system reset only once !

enjoy !

fixed : where’s the Bluetooth on my JVC KW-XR816 car stereo

Question :

I want to connect my iPhone to my JVC KW-XR816 car stereo using Bluetooth, but I can’t find the Bluetooth option in the settings menu…

What is wrong ?

 

Answer :

The problem you are encountering is probably caused by the fact that the JVC KW-XR816 car stereo doesn’t have the Bluetooth-receiver built-in… it is different from other car stereos in the respect that the Bluetooth-receiver comes as a separate USB-dongle in the product packaging…

So, find the USB-dongle in the product packaging and stick it into the USB-port on the front of the JVC KW-XR816 car stereo (or, if you slide out the entire JVC KW-XR816, you will see there’s an extra USB-port on the back of the car stereo that’s even more suited for the Bluetooth-dongle). And if the Bluetooth-dongle is plugged-in, the Bluetooth option will ‘magically’ appear in the settings menu…

If the Bluetooth-dongle is plugged-in, but the Bluetooth -option still isn’t showing in the setting menu, plug it out and then plug it back in and make sure it’s connected properly.

That’s it 😉
