There not lives , there vin slots
You can use the unit on any number of bikes to read & reset fault codes
If you wish to use the in depth service and coding functions on a bike , you must register that bikes vin to the unit
the enthusiast models come with 10 vin slots, so you could hang on to it for ten bikes assuming you stay within the BMW group
If you need or assign more than 10 vins you can get an unlock code (paid) from Hex which will turn the unit into the Pro vesion with no
vin limits
It seems a bit odd really people ask how many slots available as though more slots is better.
The reality is you only need one slot, two if you want to sell it on.
