This makes installing a HCE-TCAM-WRA a plug and play install (no splicing). Instructions are not overly detailed but if you can read a schematic, they are perfect. I wanted the dynamic guidelines and this system was the only one that offered them. My first one was defective but the second one is working fine (only been a few days so I can't comment on reliability). Steep price to pay for dynamic guidelines which in my mind is the only real advantage of the system (aside from plug and play). Of course it does save you the dealer cost of reprogramming a factory head unit if you plan to use one. That's a plus as some dealers charge $100-200 to do it. Happy with the system.
Pros: Active guidelines (later models only)
Cons: High cost
