the genaric interface called "ELM 327" for $45, and another termed "volvo chipset 232" for about $80...
Which would be better? Do I truly need the 232? And is 232 ONLY for volvo?
I'd prefer the option of also using it on my family's other cars (toyota, honda, bmw)...or are there significant advantages to the 232 for my volvo; meaning I will eventually need both?
year 2000 V70XC AWD, 94,000 miles, well maintained.
