I had my Ravelco unit installed on my TRX last week. Easy to order online, with phone follow-up. Excellent, prompt service at my home. The area franchise owner and another tech did the work. Clean, efficient and seamless. No hassle to use and Works as advertised. Cost about $629, with a AAA discount. I feel much better and safer with the system installed and will be having one installed on my inbound 392 Wrangler too.
