I bought an IM508 and the immobilizer software is identical to the IM608, however the IM508 does not come with an XP 400, APB112, Mercedes G Box 2, etc.

  When I check Function Viewer for immobilizer capability for my IM 508 I see the capability is listed there but no foot notes or asterisk denoting that in order to perform the function on the vehicle, it  will require an XP400 or other certain Non Included IM 508 accessory in order to perform the listed capability. Please supply asterisks with foot notes next to listed functions if a non included accessory is required to perform the listed function! I do not want to waste my customer's and my time if my IM508 cannot do the function listed without some non included accessories!
