I recently installed 5GD 035 280B in 2015 VW Golf Sportwagen and find the sound quality to be not as good as the original stereo. Music sounds more hollow but also less crisp. Adjusting the equalizer doesn’t seem to improve sound much. The unit works great otherwise. Is anyone else reporting sound issues and are there any possible solutions to improve sound quality?
I don’t know what your original radio was. Amplifiers and loudspeakers determine sound quality. If you don’t have an amplifier, it’s really difficult to rely on stereo to change the sound quality. The advantage of 280B is that it supports Carpaly and Android auto. Some car enthusiasts choose to install DSP to improve the sound quality, but I really lack experience in this area, and I can’t recommend good products to you.
Another solution is to install MIB2 and Volkswagen factory amplifier, which will be very expensive.
