Hello to everyone. I have Audi A4 B7 MY2008. My head unit from the stock was Audi Conecrt II+ I have swapped it to Audi RNS-E, I have bought used RNS-E and it's old one. (192C) I have very poor reception and an error in VAG-Com: 00858 - Connection; Radio ZF Output to Antenna Amplifier 007 - Short to Ground I have read about different antenna system in Conecrt and RNS-E but I can't seem to fix it, because I have amplifier 8E5035225AF and rear screen with 4 connectors, and there is no such amplifier for RNS-E for my car. Or I should just buy a newer RNS-E unit, for example with 192T? Just in case my VIN is WAUZZZ8E98A014287 Thank you.
