Where is the GPS antenna located in your GLC Was your error message the same as mine, specifically pointing to the antenna I want to avoid disassembling the wrong part of the car

Mine was under the shark fin on the roof, and yes, the error was GPS antenna related. I would suggest having a workshop take a look, given the potential for messing with the car's electronics. It's a common issue.

I appreciate the advice I'll get it sorted at the workshop I'd rather not risk making things worse. Thanks for confirming it's a common issue; that makes me feel a bit better about the potential cost. The 200€ estimate seems about right now.

I had a similar problem with my GLC's GPS. I would check the antenna connection first. Sometimes a loose wire is the cause. This could save you the cost of a new antenna.
