Baseline requirements?

I have a Lexus LS430 2005. Want to install GROM but my navigation system is not working well. Does that mean I can’t get GROM installed by a professional?

I’d appreciate any help as I’m very much a newbie. Sorry.

What is currently not working properly as far as the factory navigation system? Depending on the issue, the VLine may or may not work as intended.
