RTI needs to either provide a system that can be remotely updated, or provide a Client only software that can basically just upload an emailed file.

With our Elan g! systems I will log in make changes and be done in 5 mins. Today I drove an hr 1 way because I forgot to change the "guide" code when the cable company changed from Moxi to Moto. Granted it was my fault for not being more thorough when I installed it, but that is not the point.

As to the OP pressure your dealer to pressure RTI. Otherwise RTI will stand pat.
