Then about 2 feet of velcro (adhesive back) from Michael's for $5.
Spent 2 hours in cutting, use heat gun (high setting) to mold...
I never have any problem you've described. I have the correct update status from Carnet, including the geo-fencing. The lock/unlock function works fine.
For the charging lock, I just need to press the unlock button on either the driver or passenger door, and it almost unlock immediately...
