Hello, have a question! would like to make my CRV a bit more intressant and with a Navi retrofit Ebay 499Euro, but I’m afraid that some functions on the steering wheel no longer work or anywhere else. My contact at Honda said that it comes to problems. Is that so, or is it just banging? Does the warranty expire? Don’t know what to do now. The installation would cost 150 Euro. Who can give me advice. LG Mimmi
