- 2015 Jetta TDI SEL (purchased as "new" in May 2017).
Has anyone replaced their RNS315 radio/nav igationunit with anything better (like aftermarket). This RNS315 can't hold a radio station constant in the city of Houston. the volume/reception is up/down. If I use an app on my smartphone for local stations, it sounds great. What is with the reception? Is there an antenna solution or is this unit just not that great, or am I missing something in modern radio technology? Thanks for any help.
