Product arrived quickly, every as described. Unit fitted perfectly with no modification needed. Contacted customer support by email as a couple of issues- Bose amplifier was picking up alot of electrical interference and radio antenna adapter cable was reducing radio input signal too much - prompt response from Stella. New amplified antenna cable sent and arrived next day. Turns out my Bose system works just fine directly off the OEM, so didn't need to install the Bose amplifier! All issues resolved and very very happy with the service and after purchase support. Thank you!
