A4 cabriolet b7 reverse camera

[zen200]

Hello all,

I am finding it difficult to reverse in my newly purchased car and am wondering what options I have to assist when I need to reverse.

I have seen after market cameras like this one:

Amazon product

I know that I would have to install a screen somewhere somehow as well and as I was thinking of replacing the standard stereo for a double din after market one which has a screen inbuilt. Any suggestions ?

I have also seen after market 4 sensor kits, but I am not very comfortable to drill holes in my bumper.

Thanks for any advice in advance

Phil
