UK-POLOS.NET - THE VW Polo Forum

Hello;

Rescently i purchased an ALPINE CDE W203Ri double din unit for my 53 reg 9n polo; ever since instaling; it has never retained the memory i.e. radios stations / cd track loaction etc. I did not buy any particular block connnector as the factory standard fitted fine.

Also; At times; when i turn the car off the unit stays on and i have to manualy turn if off.

Can anyone suggest or has any ideas what i need to do to the probelms.

hi mate i think thewires need switching in the blockim having the same trouble, i should get mine sorted tomorrow. let me know if you need help

A problem I had up until this weekend when I switched headunits.

Had read online that aftermarket headunits have a different live/switched live setup to standard OE ones.
Could be solved by switching the red(live) and yellow(switched) wires on the back of the headunit DIN connectors.

Guess what...?

Something I read on the internet actually worked.

Red -> Yellow
Yellow -> Red

and POW! it gives the headunit memory.

Don't blame me tho if you use this information and blow your car up.

Does this unit fit straight in? doesnt need any surround to fit does it? cheers

it does fit straight in. i am a proud owner of this head unit. it has served me well for two years so much so that i recommended it to a friend and also bought one for my sister.
