Requested comand , dab and reverse camera for mercedes SLK r171 and reverse cam for Bmw 5 series E60. Neil did the installation , which required  a second visit. Neil was very friendly and installation was excellent. It is correct to say installation was as if it was fitted during manufacture.  I was nervous when investigating comand and dab as, dealers would not quote. I would recommend Neil for any similar requirements. Dave (Bedfordshire)
