Insure the box is appalling. When waiting for the box to be installed they set you a date, baring in mind this is my second car to have the box installed because I changed my car half way through the first policy. They give you a four hour time gap which they may or may not come in (e.g. Between 12 - 4). The first time they did not come until 5 o'clock. Despite ringing them 3 or 4 times to be put on hold for 20 minutes. The second time they gave me a time between 10 and 2o'clock. They should not be allowed to do this. If you are a busy person like me and a lot of people they should give one time slot not a 4 hour one. Very annoyed and disappointed.
