i have read with interest the i-phone mounting conversion in your X1,i would like to remove my storage compartment and replace it with the unit shown in the pitures you posted but in my case use it to mount my tomtom sat nav so i can hide the wires away behind the dash,i got the part number as you posted is this the same part for all X1's or are there variations within the E84 model,hope you can help as it's a very neat solution and a lot cheaper than the BMW option
