[macoba]

Hi there:

I have bougth a new pumpkin 7 ". 7.1. model 02306B Trough amazon, the number of 404-2647451-6686708

I have put it in a CLK 320 mercedes., In general i`m veri glad whit the unit, but i have a couple of doubts:

1. The unit have a blue wire that i think i must connect to the amplified aerial. ¿is this correct?.

2. Is there any new firmware for to actualice the unit?.

In my first impressin the unit works well, althoug the bluetooth telefone doesn`t sound clearly.

Best regards.

Hi,
1.yes,but if there is no an amplifier in your car,you can leave it alone.
2.we don't suggest you flash the unit if it works as it should.There is no big change after update the firmware.
