Thought i might ask the question here,
My mates got an a4 sline 170 tdi,
Anyway he,s just fitted an aftermarket chinese sat nav i think from a company called synter.
He,s got as far as fitting it all, (certainly isn,t plug and play as suggested), but as a few issues.
1/ although he steering wheel controls with is factory fitted unit, they do not work with his new one.
2/ when making a phone call, the person phoned can hear him, but he cannot hear them.
3/ Strange one this, the satnav thinks he's in france, instead of wales, nothing we can think of changes that.
Just to add, all the wiring as far as i know is correct and to supplied instructions.
Thanks in hand if anyone can help.
