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, or

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 : how to change my Home-location in the TomTom app for iOS ?

Question :

I recently moved to a new home, so I’ve changed my Home-location in AddressBook. But whenever I use the TomTom navigation app on my iPhone, and select Home, it still selects my old address and directs me there… not having noted that, I ended up on the wrong side of town last night…

What is wrong ?


Answer :

The for iOS has it’s own location set for ‘Home’. You probably set that up long time ago, when you started to use the app and forgot about it.

To change the Home-location setting inside the, do this :

  • open the on your iPhone
  • when you see the regular navigation map screen, swipe from left to right
  • when the “Menu” screen appears, scroll down and click on “Change Settings”
  • in the “Settings” screen that appears, click on the top line (listing your name with a green home-icon in front of it)
  • now the “Set Home Location” screen opens and you can choose a way to input a new Home-location ; these are the easiest ways of doing so :
    • click “People”, then “Contact”, then type your own name in the Search-field, select yourself when you are listed, then select your Home-location from your AddressBook
    • click “Address” and input your new home address as if it was a new destination

That’s it !

fixed : 5V 4A car adapter for Samsung Optical SmartHub SE-208BW

Question :

I have a Samsung Optical SmartHub SE-208BW (all-in-one : WiFi-DVD player, media streamer,  WiFi-router and DVD+R burner), and since it is capable of streaming DVDs and HardDisk content to my iPhone/iPad using the Samsung SmartHub iOS-app, I thought it would be a great idea to use it in my car also.

However, if I power it using the USB-cable that comes with the SmartHub, it is limited to not act as a WiFi-device. So… I need a ‘dedicated’ car-adapter for it…

But… the power needed is 5V and 4A minimum… that’s a really rare combination… and Samsung does not sell any car adapters for the SmartHub, neither do they have any recommendation on a good solution…

What options do I have ?

Answer :

The Samsung Optical SmartHub SE-208BW is a rather unique piece of equipment. Combined with an iPhone/iPad and the SmartHub-app, it is a really versatile solution …if you keep in mind that it still has some little flaws…

If you ask Samsung how to power the Samsung Optical SmartHub SE-208BW in your car, they will recommend using a cigarette-lighter-to-220V-transformer…

…that’s a stupid ‘solution’, since transforming from 12V to 220V and back to 5V is both a complete waste of energy resources and it will drain your car battery…

So… after elaborate search and testing, I’ve found a ‘real’ car adapter solution for the SmartHub ; you should create a car-adapter yourself consisting of these three parts :

1- a USB to 5V DC Barrel H power cable like this one :

USB to 5V DC Barrel H power cable

2- a USB Y-connection cable (2x USB-male to 1x USB-female) like this one :

USB Y-connection able

3- a 5V 4.2A dual-USB car adapter ; at this moment, there is only one product like this that actually works :

5V 4.2A dual-USB car adapter

If you join these 3 parts together into, you’ll have exactly the car adapter you need for the Samsung Optical SmartHub SE-208BW.

Enjoy !
